Merge branch 'tcp_bbr-more-GSO-work'
Eric Dumazet says:
====================
tcp_bbr: more GSO work
Playing with r8152 USB 1Gbit NIC, on both USB2 and USB3 slots, I found
that BBR was performing poorly, because of TSO being limited to 16KB
This patch series makes sure BBR is not under estimating number of
packets that are needed to fill the pipe when a device has suboptimal
TSO limits.
