Subject: [PATCH 2/2] wifi: mac80211: add LDPC related flags in ieee80211_bss_conf
Date: Thu, 9 Feb 2023 06:09:02 +0800	[thread overview]
Message-ID: <4e5cff1c538cbd9ecca171e0e4d6fddd87c3dfa0.1675893838.git.ryder.lee@mediatek.com> (raw)
In-Reply-To: <c1a6ef2f42e26a6e0473d4fb2ce1b572f8448d87.1675893838.git.ryder.lee@mediatek.com>

This is utilized to pass LDPC configurations from user space (i.e. hostap) to driver.
