* qlge: Fix dropping of large non-TCP/UDP frames.Ron Mercer2010-02-171-15/+5
| | | | | | | | This was found with pings that were large enough to span multiple rx buffers. The split frame logic handles this case nicely. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ll_temac: Fix MAC address configuration from userlandSteven J. Magnani2010-02-171-1/+8
| | | | | | | | | | A userland command to set the LLTEMAC MAC address, i.e. "ifconfig eth0 hw addr xx:yy:zz:pp:dd:qq", results in a device address of 00:01:xx:yy:zz:pp. Correct this. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* igb: change descriptor control thresholdsNick Nunley2010-02-171-2/+2
| | | | | | | | | | | | This change simplifies the code by setting RX_PTHRESH to 8 for all devices, as it was unlikely that there was any advantage to set it at 16 for earlier cards. Additionally TX_WTHRESH is set to 1 for the 82576 NIC to improve performance by enabling a minimal amount of write combining when writing back descriptors.
