ionic: linearize tso skb with too many frags
[ Upstream commit d2c21422323b06938b3c070361dc544f047489d7 ]
We were linearizing non-TSO skbs that had too many frags, but
we weren't checking number of frags on TSO skbs. This could
lead to a bad page reference when we received a TSO skb with
more frags than the Tx descriptor could support.
v2: use gso_segs rather than yet another division
don't rework the check on the nr_frags
Fixes: 0f3154e6bcb3 ("ionic: Add Tx and Rx handling")
