Subject: pinsched: Avoid uninitialized variable warning.
X-Git-Tag: v1.1.0~641
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=a2973b1a8b539e0f7fbd1f9fbb090b406484c1bb;p=sliver-openvswitch.git

pinsched: Avoid uninitialized variable warning.

Some compilers warn about the variable 'n_longest' in drop_packet()
being used uninitialized.  This isn't actually possible but explicitly
set it to zero to avoid spurious warnings.
