[RFC PATCH v2 net-next 0/3] tcp: add NV congestion control

[Lawrence Brakmo <brakmo@fb.com>]

This patchset adds support for NV congestion control.

The first patch replaces two arguments in the pkts_acked() function
of the congestion control modules with a struct, making it easier to
add more parameters later without modifying the existing congestion
control modules.

The second patch adds the number of bytes in_flight when a packet is sent
to the tcp_skb_cb without increasing its size.

The third patch adds NV congestion control support.
