16 years agonetlink: fix binop RHS byteorder
Patrick McHardy [Tue, 28 Jul 2009 12:17:42 +0000 (14:17 +0200)] 
netlink: fix binop RHS byteorder

The byteorder of the RHS of a binop must be set before post-processing it to
make sure it will get byteorder-switched if necessary.

Fixes invalid conntrack expression states when used with bitmasks:
