These patches add the header linux/if_ether.h and change 1500 to ETH_DATA_LEN in
some files.
Signed-off-by: Kris Katterjohn <[EMAIL PROTECTED]>
At first I wasn't going to change anything under net/ipv[46], but I then saw
that
ipv6/ip6_tunnel.c used ETH_DATA_LEN, so I went ahead and changed them, too.
A "grep -R 1500 /usr/src/linux/net" yields a few results, but these files that I
patched seem to be the ones that "fit" best with ETH_DATA_LEN.
Let me know what you think. Thanks!
