When adding new unicast steer entry, before moving qp to state ready,
actually before calling mlx4_RST2INIT_QP_wrapper(), there were added
a lot of entries with local_qpn=0 into radix tree.
This fact impacted the get_res() function and proper functioning
of resource tracker in addition to adding trash entries into radix tree.

When passing MLX4_UC_STEER=1 it was translated to value 2
after mlx4_QP_ATTACH_wrapper. Therefore in new_steering_entry()
unicast steer entries were added to index 2 of array of size 2.
Fixing this bug by shift right to one position.

Rate control algorithms are supposed to stop processing when they
encounter a rate with the index -1. Checking for rate->count not being
zero is not enough.
Allowing a rate with negative index leads to memory corruption in
ath_debug_stat_rc().
One consequence of the bug is discussed at

Driver maintains different flags for WEP, WPA, WPA2 security modes.
Appropriate flag is set using security information provided in
connect request. mwifiex_is_network_compatible() routine uses them
to check if driver's setting is compatible with AP. Association is
aborted if the routine fails.
For some corner cases, it is observed that association is failed
even for valid security information based on association history.
This patch fixes the problem by clearing previous security setting
during each association.
We should set WEP key provided in connect request as default tx key.
This missing change is also added here.

By allowing hw scan while idle, we no longer

When configuring the arp response template,
and encryption is enabled, we should add some
space and set the protected flag bit in the fc.
In order to track the encryption type, set
wlvif->encryption_type when setting an encryption key,
and reconfigure the arp response. Clear this field on
wl1271_join, as keys have to be re-configured
anyway after a join command.
Similarly, track whether QoS is configured.

FW now supports dynamic PS so we don't need to use mac80211 support.
FW will go to PSM after a specified timeout with no Rx/Tx traffic.
- Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter
- The default PS mode would be dynamic PS
- Default timeout is 100ms (same as it used to be in mac80211)
- Avoid using mac80211 APIs to disable/enable dynamic PS as we're not
using mac80211 PS control anymore.
- COEX is handled by the FW while in dynamic PS so removed
handling of SOFT_GEMINI

wl1271_tx_update_filters() is used as some workaround

Add support for two MAC addresses. If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.
If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM. If it does, we read it and derive
the two subsequent addresses for WLAN.
During production, 3 addresses are reserved per device. The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.

In order to read the MAC addresses from the fuse ROM, we need to know
the chip ID and the HW PG version. We need to know the MAC address
during probe, because that's when we register our HW with mac80211.
To prepare for that, this patch reads the chip ID and HW PG version
during probe instead of doing it at boot time. We power the chip on
briefly in order to do that.

Up till now we only needed to access the partition table in boot.c.
But to add support for reading the MAC address from the FUSE in
testmode, we will have to change the partition in testmode.c.
Thus, we move the partition table to io.c and export it via io.h. It
makes more sense to have it in the io part anyway.
