Revert "rt2x00: Endless loop on hub port power down"
This reverts commit
2ad69ac5976191e9bb7dc4044204a504653ad1bb. It
causes wireless device disappear when we get -EPROTO error form USB
request. I encounter such situation occasionally when resume form
suspend with RT3070 adapter:
[ 289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71
[ 289.639368] ieee80211 phy0: rt2800_wait_bbp_ready: Error - BBP register access failed, aborting
[ 289.639374] ieee80211 phy0: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5)
Without the patch, except printing error, device works just fine after
resume.
Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should
not have any "endless loop", though we can wait quite long when driver
is trying to communicate with the device through non functioning USB
connection. Generally the problem that commit
2ad69ac597619 solves
is kinda artificial.

iwlwifi: mvm: use private TFD queues for TDLS stations
When adding a TDLS station, allocate 4 new queues for it. Configure them
to FW and enable them. On station removal, drain the queues if needed
and disable them when empty.
Make sure to flush all packets in the private queues of TDLS stations in
the mac80211 flush() callback.

iwlwifi: mvm: disconnect TDLS peers on reconfig
When TDLS peers are present the FW will send packets on a dedicated
TID vs. the peer when performing TDLS channel-switches. The driver
configures the TID on connection to the peer and the FW is responsible
for maintaining the state of QoS seqno and PN/IV for encryption.
If the FW asserts, the driver cannot correctly reconfigure the starting
seqno/PN to the reloaded FW, thus forcing us to reconnect the peer.

Send a dedicated TDLS_CONFIG command when a TDLS peer joins/leaves. The

iwlwifi: mvm: pull SNAP header into skb->head
When we pre-populate the skb->head for the stack, we only pull
in the 802.11 header including crypto (assuming the packet isn't
short enough to be in there completely.) This is fine, but in
ieee80211_data_to_8023() we later unconditionally pull 8 more
bytes for the SNAP header and ethertype field (except for mesh
or 4-addr, where it's even more, but we don't care as much about
them).
Avoid the additional later pull by pulling in those 8 bytes here.

iwlwifi: mvm: add WEP RX hardware offload support
In the original driver, we decided to not implement WEP RX hardware
offload because of a quirk with the firmware API - it allows setting
global WEP keys that then get used for all virtual interfaces, which
is clearly wrong if more than one exists, and it allows setting per-
station keys but then separates multicast and unicast keys.
In order to implement WEP RX hardware offload, work around these
limitations by uploading each WEP key twice, once as multicast and
once as unicast, but point them both to the same key slot (offset)
and use the same key material so the slot overwrite on the second
upload doesn't actually change anything. Upon removal, also remove
the key twice so the station no longer references it.
