内核linux2.4.20,可跟rtlinux3.2打补丁 组成实时linux系统,编译内核

	Fix several bugs by distinguishing between MII
	and SYM advertising values.
	Set CSR14 autonegotiation bit for media types 2 and 4,
	where the SIA CSR setup values are not provided.

2001-05-10  Jeff Garzik  <[e-mail]>

	* media.c (tulip_select_media): Only update MII
	advertising value if startup arg < 2.

	* tulip.h: Do not enable CSR13/14/15 autoconfiguration
	for 21041.

	* tulip_core.c:
	21041: add specific code for reset, and do not set CAC bit
	When resetting media, for media table type 11 media, pass
	value 2 as 'startup' arg to select_media, to avoid updating
	MII advertising value.

2001-05-10  Jeff Garzik  <[e-mail]>

	* pnic.c (pnic_check_duplex): remove
	pnic.c (pnic_lnk_change, pnic_timer): use
	tulip_check_duplex not pnic_check_duplex.

	* media.c (tulip_check_duplex):
	Clean up to use symbolic names instead of numeric constants.
	Set TxThreshold mode as necessary as well as clearing it.
	Update csr6 if csr6 changes, not simply if duplex changes.

	(found by Manfred Spraul)

2001-05-10  Jeff Garzik  <[e-mail]>

	* 21142.c, eeprom.c, tulip.h, tulip_core.c:
	Remove DPRINTK as another, better method of
	debug message printing is available.

2001-05-09  Jeff Garzik  <[e-mail]>

	* 21142.c (t21142_lnk_change): Pass arg startup==1
	to tulip_select_media, in order to force csr13 to be
	zeroed out prior to going to full duplex mode.  Fixes
	autonegotiation on a quad-port Znyx card.
	(from Stephen Dengler)

2001-05-09  Russell King  <[e-mail]>

	* interrupt.c: Better PCI bus error reporting.

2001-04-03  Jeff Garzik  <[e-mail]>

	* tulip_core.c: Now that dev->name is only available late
	  in the probe, insert a hack to replace a not-evaluated
	  "eth%d" string with an evaluated "tulip%d" string.
	  Also, remove obvious comment and an indentation cleanup.

2001-04-03  Jeff Garzik  <[e-mail]>

	* tulip_core.c: If we are a module, always print out the
	  version string.  If we are built into the kernel, only print
	  the version string if at least one tulip is detected.

2001-04-03  Jeff Garzik  <[e-mail]>

	Merged from Becker's tulip.c 0.92t:

	* tulip_core.c: Add support for Conexant LANfinity.

2001-04-03  Jeff Garzik  <[e-mail]>

	* tulip_core.c: Only suspend/resume if the interface
	  is up and running.  Use alloc_etherdev and pci_request_regions.
	  Spelling fix.

2001-04-03  Jeff Garzik  <[e-mail]>

	* tulip_core.c: Remove code that existed when one or more of
	  the following defines existed.  These defines were never used
	  by normal users in practice: TULIP_FULL_DUPLEX,
	  TULIP_DEFAULT_MEDIA, and TULIP_NO_MEDIA_SWITCH.

	* tulip.h, eeprom.c: Move EE_* constants from tulip.h to eeprom.c.
	* tulip.h, media.c: Move MDIO_* constants from tulip.h to media.c.

	* media.c: Add barrier() to mdio_read/write's PNIC status check
	  loops.

2001-04-03  Jeff Garzik  <[e-mail]>

	Merged from Becker's tulip.c 0.92t:

	* tulip.h: Add MEDIA_MASK constant for bounding medianame[]
	  array lookups.
	* eeprom.c, media.c, timer.c, tulip_core.c: Use it.

	* media.c, tulip_core.c: mdio_{read,write} cleanup.  Since this
	  is called [pretty much] directly from ioctl, we mask
	  read/write arguments to limit the values passed.
	  Added mii_lock.  Added comet_miireg2offset and better
	  Comet-specific mdio_read/write code.	Pay closer attention
	  to the bits we set in ioctl.	Remove spinlocks from ioctl,
	  they are in mdio_read/write now.  Use mask to limit
	  phy number in tulip_init_one's MII scan.

2001-04-03  Jeff Garzik  <[e-mail]>

	Merged from Becker's tulip.c 0.92t:

	* 21142.c, tulip_core.c: PNIC2 MAC address and NWay fixes.
	* tulip.h: Add FullDuplex constant, used in above change.

2001-04-03  Jeff Garzik  <[e-mail]>

	* timer.c: Do not call netif_carrier_{on,off}, it is not used in
	  the main tree.  Leave code in, disabled, as markers for future
	  carrier notification.

2001-04-03  Jeff Garzik  <[e-mail]>

	Merged from Becker's tulip.c 0.92t, except for the tulip.h
	whitespace cleanup:

	* interrupt.c: If Rx stops, make sure to update the
	  multicast filter before restarting.
	* tulip.h: Add COMET_MAC_ADDR feature flag, clean up flags.
	  Add Accept* Rx mode bit constants.
	  Add mc_filter[] to driver private struct.
	* tulip_core.c: Add new Comet PCI id 0x1113:0x9511.
	  Add COMET_MAC_ADDR feature flag to comet entry in board info array.
	  Prefer to test COMET_MAC_ADDR flag to testing chip_id for COMET,
	  when dealing with the Comet's MAC address.
	  Enable Tx underrun recovery for Comet chips.
	  Use new Accept* constants in set_rx_mode.
	  Prefer COMET_MAC_ADDR flag test to chip_id test in set_rx_mode.
	  Store built mc_filter for later use in intr handler by Comets.

2001-04-03  Jeff Garzik  <[e-mail]>

	* tulip_core.c: Use tp->cur_tx when building the
	  setup frame, instead of assuming that the setup
	  frame is always built in slot zero.  This case is
	  hit during PM resume.

2001-04-03  Jeff Garzik  <[e-mail]>

	* *.c: Update file headers (copyright, urls, etc.)
	* Makefile: re-order to that chip-specific modules on own line
	* eeprom.c: BSS/zero-init cleanup (Andrey Panin)
	* tulip_core.c: merge medianame[] update from tulip.c.
	  Additional arch-specific rx_copybreak, csr0 values. (various)

2001-02-20  Jeff Garzik  <[e-mail]>

	* media.c (tulip_select_media): No need to initialize
	new_csr6, all cases initialize it properly.

2001-02-18  Manfred Spraul  <[e-mail]>

	* interrupt.c (tulip_refill_rx): Make public.
	If PNIC chip stops due to lack of Rx buffers, restart it.

	with software timers.
	* pnic.c (pnic_check_duplex): New function, PNIC-specific
	version of tulip_check_duplex.
	(pnic_lnk_change): Call pnic_check_duplex.  If we use an
	external MII, then we mustn't use the internal negotiation.
	(pnic_timer): Support Rx refilling on work overflow in
	interrupt handler, as PNIC doesn't support a h/w timer.
	* tulip_core.c (tulip_tbl[]): Modify default csr6

2001-02-11  Jeff Garzik  <[e-mail]>

	* tulip_core.c (tulip_init_one): Call pci_enable_device
	to ensure wakeup/resource assignment before checking those
	values.
	(tulip_init_one): Replace PCI ids with constants from pci_id.h.
	(tulip_suspend, tulip_resume, tulip_remove_one): Call
	pci_power_on/off (commented out for now).

2001-02-10  Jeff Garzik  <[e-mail]>

	* tulip.h: Add CFDD_xxx bits for Tulip power management
	* tulip_core.c (tulip_set_power_state): New function,
	manipulating Tulip chip power state where supported.
	(tulip_up, tulip_down, tulip_init_one): Use it.

2001-02-10  Jeff Garzik  <[e-mail]>

	* tulip_core.c (tulip_tx_timeout): Call netif_wake_queue
	to ensure the next Tx is always sent to us.

2001-01-27  Jeff Garzik  <[e-mail]>

	* tulip_core.c (tulip_remove_one): Fix mem leak by freeing
	tp->media_tbl.  Add check for !dev, reformat code appropriately.

2001-01-27  Jeff Garzik  <[e-mail]>

	* tulip_tbl[]: Comment all entries to make order and chip_id
	relationship more clear.
	* tulip_pci_tbl[]: Add new Accton PCI id (COMET chipset).

2001-01-16  Jeff Garzik  <[e-mail]>

	* tulip_core.c: static vars no longer explicitly
	initialized to zero.
	* eeprom.c (tulip_read_eeprom): Make sure to delay between
	EE_ENB and EE_ENB|EE_SHIFT_CLK.  Merged from becker tulip.c.

2001-01-05  Peter De Schrijver  <[e-mail]>

	* eeprom.c (tulip_parse_eeprom): Interpret a bit more of 21142
	extended format type 3 info blocks in a tulip SROM.

        * eeprom.c, timer.c, tulip.h, tulip_core.c: Merge support
	for the Davicom's quirks into the main tulip.
	Patch by Tobias Ringstrom

2000-11-08  Jim Studt  <[e-mail]>

	* eeprom.c (tulip_parse_eeprom):  Check array bounds for
	medianame[] and block_name[] arrays to avoid oops due
	to bad values returned from hardware.

2000-11-02  Jeff Garzik  <[e-mail]>

	* tulip_core.c (set_rx_mode): This is synchronized via
	dev->xmit_lock, so only the queueing of the setup frame needs to
	be locked, against tulip_interrupt.

2000-11-02  Alexey Kuznetov  <[e-mail]>

	* timer.c (tulip_timer): Call netif_carrier_{on,off} to report
	link state to the rest of the kernel, and userspace.
	* interrupt.c (tulip_interrupt): Remove tx_full.
	* tulip.h: Likewise.
	* tulip_core.c (tulip_init_ring, tulip_start_xmit, set_rx_mode):
	Likewise.

2000-10-18  Jeff Garzik  <[e-mail]>

	* tulip_core.c: (tulip_init_one) Print out ethernet interface
	on error.  Print out a message when pci_enable_device fails.
	Handle DMA alloc failure.

2000-10-18  Jeff Garzik  <[e-mail]>

	* Makefile: New file.
	* tulip_core.c (tulip_init_one): Correct error messages
	on PIO/MMIO region reserve failure.
	(tulip_init_one) Add new check to ensure that PIO region is
	sufficient for our needs.
