Subject: [PATCH net-next] net: remove redundant code in dev_hard_start_xmit()
From: Eric Dumazet <edumazet@...gle.com>
This reverts commit 068a2de57ddf4f4 (net: release dst entry while
cache-hot for GSO case too)
Before GSO packet segmentation, we already take care of skb->dst if it
can be released.
There is no point adding extra test for every segment in the gso loop.
