From: Manikanta Pubbisetty <mpubbise@xxxxxxxxxxxxxxxx> This patch set adds a new transmit data path to offload 802.11 header encap to driver/hardware. Drivers having support for ieee80211 header encap and other offload functionalities which can't be done before encap can make use of this new data path. Currently it is implemented for STA and AP interface type, this can be extend other interface types like adhoc. This patchset only adds support for tx in ethernet frame format and receive can happen in 802.11 format with existing rx framework. With ath10k driver changes using this new Tx/Rx path, 10 - 15% CPU usage and upto ~20Mbps TCP performance improvements are observed with this ethernet data path.
