Subject: [RFCv2 bluetooth-next 01/19] ieee802154: 6lowpan: remove headroom check
Date: Sun, 7 Aug 2016 16:30:38 +0200 [thread overview]
Message-ID: <20160807143056.3116-2-aar@pengutronix.de> (raw)
In-Reply-To: <20160807143056.3116-1-aar@pengutronix.de>
This patch removes unnessary headroom check. We will check that value
while register net device that we have such headroom for placing address
information at the headroom of skb.
Signed-off-by: Alexander Aring <aar@pengutronix.de>
