Subject: selftests: nci: Fix the code for next nlattr offset
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=78a7b2a8a0fa31f63ac16ac13601db6ed8259dfc;p=uclinux-h8%2Flinux.git

selftests: nci: Fix the code for next nlattr offset

nlattr could have a padding for 4 bytes alignment. So next nla's offset
should be calculated with a padding.
