2014-05-07iwlwifi: pcie: disable interrupts upon PCIe allocEmmanuel Grumbach
In case RFKILL is in KILL position, the NIC will issue an interrupt straight away. This interrupt won't be sent because it is masked in the hardware. But if our interrupt service routine is called for another reason (SHARED_IRQ), then we'll look at the interrupt cause and service it. This can cause bad things if we are not ready yet. Explicitly clean the interrupt cause register to make sure we won't service anything before we are ready to.

2014-05-06iwlwifi: mvm: rs: choose correct expected tpt tableEyal Shapira
The expected throughput table used when estimating a new column depends on the channel bandwidth. When switching from legacy to siso or mimo the wrong expected throughput table was used as it was chosen based on the the channel bandwidth in legacy which is always 20Mhz. Instead it should be chosen based on the current sta bandwidth which could be also 40Mhz or 80Mhz. When enabling MCS9 this bug leads to a problem where the max expected throughput of the siso or mimo column is 0 as MCS9 isn't supported in 20Mhz. This in turns prevents switching to siso or mimo.

Beginning with kernel 3.13, this driver fails on some systems. The problem was bisected to: Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac Author: Felix Fietkau <nbd@openwrt.org> Title: mac80211: send control port protocol frames to the VO queue There is noting wrong with the above commit. The regression occurs because V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to modify the rtl8192se routine that sets the correct transmit queue.
