Subject: [RFC] zero-copy AMSDU processing
Date: Thu, 19 Feb 2015 12:51:10 +0200 [thread overview]
Message-ID: <1708052.J876aMsZU2@lx-wigig-72> (raw)
I am looking for ideas how can one process AMSDU in the software, without copying data.
Current implementation like ieee80211_amsdu_to_8023s() do copy packet data.
Assume I got in the driver, MPDU that is AMSDU containing several MSDU's.
It is in the single memory buffer that was allocated for DMA.
Can I construct skb's per MSDU with minimal data copy, having most of the
original data in place? Any ideas for this?
Thanks, Vladimir.
