correctly done.

Subject: [PATCH] gro: fix unprocessed IPv4 packets
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 5c762a58c3fa81e232a5cba8087577be1a593c33 ]

gro_vxlan_tcp4_tbl_timeout_flush() is called without taking into account
that first entries in pkts[] can be already occupied by
un-processed packets.

Fixes: 74080d7dcf31 ("gro: support IPv6 for TCP")
