Eric Dumazet 572be9bf9d tcp: increase tcp_rmem[2] to 32 MB 
Last change to tcp_rmem[2] happened in 2012, in commit b49960a05e
("tcp: change tcp_adv_win_scale and tcp_rmem[2]")

TCP performance on WAN is mostly limited by tcp_rmem[2] for receivers.

After this series improvements, it is time to increase the default.
