From ae02c8719aab19bf311b6ce2881feb844456297e Mon Sep 17 00:00:00 2001 From: Vasanthakumar Thiagarajan Date: Fri, 9 Sep 2016 17:25:22 +0300 Subject: ath10k: add provision for Rx descriptor abstraction There are slight differences in Rx hw descriptor information among different chips. So far driver does not use those new information for any functionalities, but there is one important information which is available from QCA99X0 onwards to indicate the number of bytes that hw padded at the begining of the rx payload and this information is needed to undecap the rx packet. Add an abstraction for Rx desc to make use of the new desc information available. The callback that this patch defines to retrieve the padding bytes will be used in follow-up patch.
