Subject: [PATCH 3/9] backports: genetlink: Add genlmsg_parse()
Date: Tue, 21 Apr 2020 00:16:09 +0200
Message-ID: <20200420221615.14734-4-hauke@hauke-m.de> (raw)
In-Reply-To: <20200420221615.14734-1-hauke@hauke-m.de>

This adds the genlmsg_parse() function to the netlink backport. This was
added in upstream commit 8cb081746c03 ("netlink: make validation more
configurable for future strictness").

This function is used by the mac80211_hwsim driver.
