Subject: ndisc: Fix padding error in link-layer address option.
X-Git-Tag: omap-for-v3.8/fixes-for-merge-window-v4-signed~32^2~2

ndisc: Fix padding error in link-layer address option.

If a natural number n exists where 2 + data_len <= 8n < 2 + data_len + pad,
post padding is not initialized correctly.

(Un)fortunately, the only type that requires pad is Infiniband,
whose pad is 2 and data_len is 20, and this logical error has not
become obvious, but it is better to fix.

Note that ndisc_opt_addr_space() handles the situation described
above correctly.
