Subject: net/ice: fix unsafe tailq element removal
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=eec6a3394e4a399d40916685f113bdec33a55704;p=dpdk.git

net/ice: fix unsafe tailq element removal

TAILQ_FOREACH macro is not safe to remove elements
during iterating tailq lists. Replace it with
TAILQ_FOREACH_SAFE.

Fixes: d76116a4678f ("net/ice: add generic flow API")
