For 2-antenna combo card, the signal of the neighbor antenna could be over noise level and cause be severe interference. So we monitor the rssi and turn off one of the antennas when the other is transmitting and the rssi level is beyond a threshold. Signed-off-by:

When wifi is in concurrent mode, we can not distinguish if it is the real PS or just a fake one by sending null data, so we turn it off in case of miracast scenario. Signed-off-by:

During hw initialisation, wifi may be ready after bt has already been ready, which causes bt to act abnormally. To avoid this, set GNT_BT to high during hw init. Signed-off-by:

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:

The variable is for PS tdma duration adjust, so rename it to clearly to specify its usage. Signed-off-by:
-
Yan-Hsuan Chuang authored
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:
