2008-08-07atl1: deal with hardware rx checksum bugJay Cliburn1-8/+11
The L1 hardware contains a bug that flags a fragmented IP packet as having an incorrect TCP/UDP checksum, even though the packet is perfectly valid and its checksum is correct. There's no way to distinguish between one of these good packets and a packet that actually contains a TCP/UDP checksum error, so all we can do is allow the packet to be handed up to the higher layers and let it be sorted out there. Add a comment describing this condition and remove the code that currently fails to handle what may or may not be a checksum error.

So, remove the netif_{wake,stop}_queue() calls in the link check code, and add the necessary netif_start_queue() call to atl1_up(). Signed-off-by: David S. Miller <davem@davemloft.net>

2008-06-17atl1: relax eeprom mac address error checkRadu Cristescu1-1/+0
The atl1 driver tries to determine the MAC address thusly: - If an EEPROM exists, read the MAC address from EEPROM and validate it. - If an EEPROM doesn't exist, try to read a MAC address from SPI flash. - If that fails, try to read a MAC address directly from the MAC Station Address register. - If that fails, assign a random MAC address provided by the kernel. We now have a report of a system fitted with an EEPROM containing all zeros where we expect the MAC address to be, and we currently handle this as an error condition. Turns out, on this system the BIOS writes a valid MAC address to the NIC's MAC Station Address register, but we never try to read it because we return an error when we find the all- zeros address in EEPROM. This patch relaxes the error check and continues looking for a MAC address even if it finds an illegal one in EEPROM.
