Commit cecda693a969816bac5e470e1d9c9c0ef5567bca ("net: keep original skb
which only needs header checking during software GSO") keeps the original
skb for packets that only needs header check, but it doesn't drop the
packet if software segmentation or header check were failed.

Fixes cecda693a969816bac5e470e1d9c9c0ef5567bca
(net: keep original skb which only needs header checking during software GSO)

Please correct this fixes tag, it should be of the form:

Fixes: $(SHA1) ("header text of commit message")

The SHA1 ID should be reduced to 12 digits of significance.
