Subject: [PATCH] Documentation: fix udp_wmem_min in ip-sysctl.rst
Git-commit: c6b10de537b904fb70522d8cc4600c2f11246c93
Patch-mainline: v5.19-rc8
References: git-fixes

UDP doesn't support tx memory accounting, and sysctl udp_wmem_min
is not really used anywhere. So we should fix the description in
ip-sysctl.rst accordingly.

Fixes: 95766fff6b9a ("[UDP]: Add memory accounting.")
