Subject: tcp: fix tcp_min_tso_segs sysctl
From: Eric Dumazet <edumazet@xxxxxxxxxx>
commit d24f511b04b8b159b705ec32a3b8782667d1b06a upstream.
tcp_min_tso_segs is now stored in u8, so max value is 255.
255 limit is enforced by proc_dou8vec_minmax().
We can therefore remove the gso_max_segs variable.
Fixes: 47996b489bdc ("tcp: convert elligible sysctls to u8")
