Subject: [PATCH net-next 0/2] 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.

Eric Dumazet (2):
  tcp_bbr: better deal with suboptimal GSO (II)
  tcp_bbr: remove bbr->tso_segs_goal
