Subject: [PATCH iw,v2 3/3] iw: fix EHT capabilities on Big Endian platforms
Date: Sat, 5 Apr 2025 20:48:07 +0200 [thread overview]
Message-ID: <20250405184807.701728-4-olek2@wp.pl> (raw)
In-Reply-To: <20250405184807.701728-1-olek2@wp.pl>
IE fields are encoded in Little Endian and are not correctly
printed on Big Endian platforms.
Fixes: 5a71b722270c ("iw: Print local EHT capabilities")
