2019-11-20iwlwifi: pcie: fix support for transmitting SKBs with fraglistJohannes Berg
When the implementation of SKBs with fraglist was sent upstream, a merge-damage occurred and half the patch was not applied. This causes problems in high-throughput situations with AX200 devices, including low throughput and FW crashes. Introduce the part that was missing from the original patch. Fixes: 0044f1716c4d ("iwlwifi: pcie: support transmitting SKBs with fraglist") Cc: stable@vger.kernel.org # 4.20+ Signed-off-by: Johannes Berg <johannes.berg@intel.com> [ This patch was created by me, but the original author of this code is Johannes, so his s-o-b is here and he's marked as the author of the patch. ] Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2019-11-15iwlwifi: mvm: don't skip mgmt tid when flushing all tidsHaim Dreyfuss
There are various of flows which require tids flushing (disconnection, suspend, etc...). Currently, when the driver instructs the FW to flush he masks all the data tids(0-7). However, the driver doesn't set the management tid (#15) which cause the FW not to flush it. When the FW tries to remove the mgmt queue he throws an assert since it is not an empty queue. instead of just set only the data tids set everything and let the FW ignore the invalid tids.
