	Description : smsc9118 driver 

	History	    :
		03-16-05 WH			First Release
		08-12-05 MDG		ver 1.01 
			- add LED1 inversion, add PHY work around
		11-07-05 WH			ver 1.02
			- Fixed middle buffer handling bug
			  (Driver didn't handle middle buffers correctly if it is less than 
               4bytes size)
			- workaround for Multicast bug
			- Workaround for MAC RXEN bug
		11-17-05 WH			ver 1.03
			- 1.02 didn't have 1.01 patches
			- 1.03 is 1.02 + 1.01
		12-06-05 WH			ver 1.04
			- Fixed RX doesn't work on Silicon A1 (REV_ID = 0x011x0002)
			- Support SMSC9118x/117x/116x/115x family
		02-27-05 WH			ver 1.05
			- Fixing External Phy bug that doesn't work with 117x/115x
		03-23-05 WH			ver 1.06
			- Put the variable to avoid PHY_WORKAROUND for External PHY
			- Change product name to 9118x->9218, 9115x->9215
		07-26-06 WH, MDG, NL		ver 1.07
			- Add RXE and TXE interrupt handlers
			- Workaround Code for direct GPIO connection from 9118 family 
			  Interrupt (Level Interrupt -> Edge Interrupt)
			- Change GPT interrupt interval to 200mSec from 50mSec
			- clean up un-used SH3 code
		08-25-06  WH, MDG, NL       ver 1.08
		    - Fixed RXE and TXE interrupt handlers bug
			- support for direct and nondirect Interrupt
