The ibm_newemac driver requires ether_crc to be defined. Apparently it is possible to generate a .config without CONFIG_CRC32 set which causes the following link errors if IBM_NEW_EMAC is selected: LD .tmp_vmlinux1 drivers/built-in.o: In function `emac_hash_mc': core.c:(.text+0x2f524): undefined reference to `crc32_le' core.c:(.text+0x2f528): undefined reference to `bitrev32' make: *** [.tmp_vmlinux1] Error 1 This patch has IBM_NEW_EMAC select CRC32 so we don't hit this error.

This driver supports the IBM EMAC family of Ethernet controllers

typically found on 4xx embedded PowerPC chips, but also on the

Axon southbridge for Cell.

Additional receive skb headroom. Note, that driver
|

will always reserve at least 2 bytes to make IP header
|

aligned, so usually there is no need to add any additional
|
|
headroom.

If unsure, set to 0.
