Emmanuel Grumbach 6eb5e529d7 iwlwifi: pcie: build an A-MSDU using TSO core ... When the op_mode sends an skb whose payload is bigger than MSS, PCIe will create an A-MSDU out of it. PCIe assumes that the skb that is coming from the op_mode can fit in one A-MSDU. It is the op_mode's responsibility to make sure that this guarantee holds. Additional headers need to be built for the subframes. The TSO core code takes care of the IP / TCP headers and the driver takes care of the 802.11 subframe headers. These headers are stored on a per-cpu page that is re-used for all the packets handled on that same CPU. Each skb holds a reference to that page and releases the page when it is reclaimed. When the page gets full, it is released and a new one is allocated. Since any SKB that doesn't go through the fast-xmit path of mac80211 will be segmented, we can assume here that the packet is not WEP / TKIP and has a proper SNAP header.
