Subject: [PATCH] Update embedded copy of ethtool.h from kernel 2.6.30

Commit 0c09c1a49cc7b819b33566a49d9901f7cfdd6889 in the Linux kernel
added a new field mdio_support inside the struct ethtool_cmd,
changing the struct size for architectures that does not pad structs.
(for example the CRIS architecture)

This size mismatch lead to the ethtool_cmd struct being written
as 44 bytes in the kernel, but only 43 bytes allocated on stack,
overwriting one byte in the stack frame.

Update the ethtool copy of the definition to match the 2.6.30 kernel.
