Subject: net/iavf: fix address of first segment
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ba38f91468a896d9363e92261cbf17c6517e098a;p=dpdk.git

net/iavf: fix address of first segment

This patch fixes (dereference after null check) coverity issue.
The address of first segmented packets was not set correctly during
reassembling packets which led to this issue.

Coverity issue: 343447
Fixes: 319c421f3890 ("net/avf: enable SSE Rx Tx")
