From 265b2099c7715a3432eef00acd1faea7cbc1eb25 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 18 Sep 2024 11:53:06 +1000 Subject: tcp: Simplify ifdef logic in tcp_update_seqack_wnd() This function has a block conditional on !snd_wnd_cap shortly before an snd_wnd_cap is statically false). Therefore, simplify this down to a single conditional with an else branch. While we're there, fix some improperly indented closing braces.
