* ks8851: companion eeprom access through ethtoolSebastien Jan2010-05-061-0/+114
| | | | | | | | | | | | | Accessing ks8851 companion eeprom permits modifying the ks8851 stored MAC address. Example how to change the MAC address using ethtool, to set the 01:23:45:67:89:AB MAC address: $ echo "0:AB8976452301" | xxd -r > mac.bin $ sudo ethtool -E eth0 magic 0x8870 offset 2 < mac.bin Signed-off-by: Sebastien Jan <s-jan@ti.com> Signed-off-by: David S.

* KS8851: Fix ks8851_set_rx_mode() for IFF_MULTICASTBen Dooks2009-10-211-1/+1
| | | | | | | | | | | | | | | In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting the RXCR1_AE bit by accident. This meant that all unicast frames where being accepted by the device. Remove RXCR1_AE from this case. Note, RXCR1_AE was also masking a problem with setting the MAC address properly, so needs to be applied after fixing the MAC write order. Fixes a bug reported by Doong, Ping of Micrel. This version of the patch avoids setting RXCR1_ME for all cases. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
* KS8851: Fix MAC address write orderBen Dooks2009-10-211-4/+33
| | | | | | | | | | | | The MAC address register was being written in the wrong order, so add a new address macro to convert mac-address byte to register address and a ks8851_wrreg8() function to write each byte without having to worry about any difficult byte swapping. Fixes a bug reported by Doong, Ping of Micrel. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
* KS8851: Add soft reset at probe timeBen Dooks2009-10-211-0/+3
| | | | | | | | | | | | Issue a full soft reset at probe time. This was reported by Doong Ping of Micrel, but no explanation of why this is necessary or what bug it is fixing. Add it as it does not seem to hurt the current driver and ensures that the device is in a known state when we start setting it up. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.
