I've sent this patch some days ago to Bart, but with no answer...

Sorry about that.

When trying to do

	# ebtables -A FORWARD --among-src 0:12:34:56:78:9a=192.168.0.10 -j ACCEPT

on x86_64 box the ebt_among->check() callback warns me that

	ebtables: among: wrong size: 1060 against expected 1056, rounded to 1056

So the suggested fix is to move the alignment in the kernel. After
the fix the rule is added and appears in the ebtables -L output.

It seems the kernel is correct and userspace is doing it
wrong, so I think userspace should be fixed instead.
The problem with your patch is that is causes misalignment
for following structures that contain u64 members.

Pavel, please try the attached userspace patch to see if it fixes the
problem (and let me know the result).

cheers,
Bart
