If bt is queing, we need to set the packet priority properly. Originally we only consider if wifi was connected or not, but now we also consider if bt is under abnormal scan or wifi is scanning, roaming or linking, and set the coex table. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Suggested-by:

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. Signed-off-by:

Benjamin Herrenschmidt says: ==================== ftgmac100: Rework batch 4 - Misc This is v2 of the fourth batch of updates to the ftgmac100 driver. This is a bunch of misc cleanups and fixes, such as properly disabling HW checksum generation on AST2400 where it's known to be broken and some chip init updates. This also adds the ability to turn HW checksum on/off and configure the ring sizes via ethtool. v2 Fixes patch 1/10 (NETIF_F_HW_CSUM conversion) The next (and last) batch will add a few more "features" such as netpoll, multicast/promist, vlan offload... ==================== Signed-off-by: -

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.

smc specifies IB_SEND_INLINE for IB_WR_SEND ib_post_send calls, but provides a mapped buffer to be sent. This is inconsistent, since IB_SEND_INLINE works without mapped buffer. Problem has not been detected in the past, because tests had been limited to Connect X3 cards from Mellanox, whose mlx4 driver just ignored the IB_SEND_INLINE flag. For now, the IB_SEND_INLINE flag is removed. Signed-off-by:

State SMC_CLOSED should be reached only, if ConnClosed has been sent to the peer. If ConnClosed is received from the peer, a socket with shutdown SHUT_WR done, switches errorneously to state SMC_CLOSED, which means the peer socket is dangling. The local SMC socket is supposed to switch to state APPFINCLOSEWAIT to make sure smc_close_final() is called during socket close. Signed-off-by:

Several state changes occur during SMC socket closing. Currently state changes triggered locally occur in process context with lock_sock() taken while state changes triggered by peer occur in tasklet context with bh_lock_sock() taken. bh_lock_sock() does not wait till a lock_sock(() task in process context is finished. This may lead to races in socket state transitions resulting in dangling SMC-sockets, or it may lead to duplicate SMC socket freeing. This patch introduces a closing worker to run all state changes under lock_sock(). Signed-off-by:

If peer indicates write_blocked, the cursor state of the received data should be send to the peer immediately (in smc_tx_consumer_update()). Afterwards the write_blocked indicator is cleared. If there is no free slot for another write request, sending is postponed to worker smc_tx_work, and the write_blocked indicator is not cleared. Therefore another clearing check is needed in smc_tx_work(). Signed-off-by:
