Subject: [PATCH net-next 0/2] net: remove two MAX_SKB_FRAGS dependencies

From: Eric Dumazet <edumazet@...gle.com>

My first series for BIG TCP met two issues that various bots pointed out,
because of MAX_SKB_FRAGS going from 17 to 45.

- typhoon driver would emit a compile error if MAX_SKB_FRAGS > 32

- include/linux/skmsg.h had a similar issue when MAX_SKB_FRAGS is
slightly over BITS_PER_LONG, so the build broke on 32bit arches.

This patch series is meant to be merged before BIG TCP one,
in order to keep the latter not too big.

  net: typhoon: implement ndo_features_check method
  skmsg: convert struct sk_msg_sg::copy to a bitmap
