Subject: [RESEND 9/9] ath11k: optimize ath11k_hal_tx_status_parse
Date: Wed,  4 Dec 2019 06:37:13 +0100	[thread overview]
Message-ID: <20191204053713.3064-10-john@phrozen.org> (raw)
In-Reply-To: <20191204053713.3064-1-john@phrozen.org>

Moving the function into dp_tx.c allows gcc to optimize the code better
and also avoid chace invalidates and context switches.
