In addition to standard Ethernet header (destination HW address, source HW address, frame size and protocol), buff_index is added. This variable is used by higher level protocols (IP, ARP or other) to initialize reading of the Ethernet packet by invoking NETWORK_RECEIVE_INITIALIZE macro to initialize reading of the data carried in the Ethernet packet ( not the Ethernet header itself!). <p><p>Definition at line <a class="el" href="ethernet_8h-source.html#l00142">142</a> of file <a class="el" href="ethernet_8h-source.html">ethernet.h</a>.<table border=0 cellpadding=0 cellspacing=0><tr><td></td></tr><tr><td colspan=2><br><h2>Data Fields</h2></td></tr><tr><td nowrap align=right valign=top>UINT8 </td><td valign=bottom><a class="el" href="structethernet__frame.html#m0">destination</a> [ETH_ADDRESS_LEN]</td></tr><tr><td nowrap align=right valign=top>UINT8 </td><td valign=bottom><a class="el" href="structethernet__frame.html#m1">source</a> [ETH_ADDRESS_LEN]</td></tr><tr><td nowrap align=right valign=top>UINT16 </td><td valign=bottom><a class="el" href="structethernet__frame.html#m2">frame_size</a></td></tr><tr><td nowrap align=right valign=top>UINT16 </td><td valign=bottom><a class="el" href="structethernet__frame.html#m3">protocol</a></td></tr><tr><td nowrap align=right valign=top>UINT16 </td><td valign=bottom><a class="el" href="structethernet__frame.html#m4">buf_index</a></td></tr></table><hr><h2>Field Documentation</h2><a name="m0" doxytag="ethernet_frame::destination"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> UINT8 ethernet_frame::destination[ETH_ADDRESS_LEN] </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>destination hardware address as read from the received ethernet packet <p>Definition at line <a class="el" href="ethernet_8h-source.html#l00144">144</a> of file <a class="el" href="ethernet_8h-source.html">ethernet.h</a>.<p>Referenced by <a class="el" href="ethernet_8c-source.html#l00482">NE2000ReceiveFrame()</a>, <a class="el" href="ethernet_8c-source.html#l00608">NE2000WriteEthernetHeader()</a>, and <a class="el" href="ip_8c-source.html#l00115">process_ip_in()</a>. </td> </tr></table><a name="m1" doxytag="ethernet_frame::source"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> UINT8 ethernet_frame::source[ETH_ADDRESS_LEN] </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>source hardware address as read from the received ethernet packet <p>Definition at line <a class="el" href="ethernet_8h-source.html#l00148">148</a> of file <a class="el" href="ethernet_8h-source.html">ethernet.h</a>.<p>Referenced by <a class="el" href="ethernet_8c-source.html#l00482">NE2000ReceiveFrame()</a>, <a class="el" href="ethernet_8c-source.html#l00608">NE2000WriteEthernetHeader()</a>, and <a class="el" href="ip_8c-source.html#l00115">process_ip_in()</a>. </td> </tr></table><a name="m2" doxytag="ethernet_frame::frame_size"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> UINT16 ethernet_frame::frame_size </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>size of the received Ethernet packet <p>Definition at line <a class="el" href="ethernet_8h-source.html#l00152">152</a> of file <a class="el" href="ethernet_8h-source.html">ethernet.h</a>.<p>Referenced by <a class="el" href="ethernet_8c-source.html#l00482">NE2000ReceiveFrame()</a>, <a class="el" href="arp_8c-source.html#l00116">process_arp()</a>, and <a class="el" href="ip_8c-source.html#l00115">process_ip_in()</a>. </td> </tr></table><a name="m3" doxytag="ethernet_frame::protocol"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> UINT16 ethernet_frame::protocol </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>protocol field of the Ethernet header.
