When driver is going to sleep, it does not leave LPS/IPS, thus the BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex needs to clear the IPS/LPS state when it receives a pnp notify, then it can properly set up the hw when driver wakes up.

For time division multiple access, the wifi and bt take turns to transmit, but we need to let AP know that wifi is under standby mode by sending null data to "pretend" entering power saving state using lps rpwm. But, the fw does not know if it is the actual power saving mode or just a fake one to cheat to the AP. Hence, before fw setting the tdma duration, the fw needs the driver to check the power saving state first.

Systems with 64 bit DMA at least partially require buffers to be used for DMA to be 8-byte-aligned. One example is Amlogic Meson GX. Switching the MMC/SDIO driver for this platform to SG DMA mode resulted in problems due to unaligned buffers. Fortunately the brcmfmac driver has a global define for the alignment. Changing it to 8 fixed the issues with Meson GX.

A driver may use build_skb() for received packets. These SKBs then have a head_frag. Since commit d7e8883c ("net: make GRO aware of skb->head_frag"), GRO may build frag_list SKBs out of head_frag received SKBs. In such a case, the chained SKBs end up with a head_frag. Commit 07b26c94 ("gso: Support partial splitting at the frag_list pointer") adds partial segmentation of frag_list SKB chains into individual SKBs. However, this is not done if the chained SKBs have any linear part, because the device may not be able to DMA the private linear buffer. A chained frag_list SKB with head_frag is wrongfully detected in this case as having a private linear part and thus falls back to software GSO, while in fact the linear part is backed by a DMA page just like any other frag. This causes low performance when forwarding those packets that were built with build_skb() Allow partial segmentation at the frag_list pointer for chained SKBs with head_frag. Note that such SKBs can only be created by GRO, when applied to received packets with head_frag. Also note that this change only affects the data path that performs the partial segmentation at frag_list pointer, and not any of the other more common data paths.

We found out that HW checksum generation only works from AST2500 onward. This disables it on AST2400 and removes the "no-hw-checksum" properties in the device-trees. The problem we had wasn't related to NC-SI. Also rework the logic testing for that property so it can be used to disable HW checksum generation and checking regardless of whether NC-SI is used or not in case other variants out there need this.
