Jakub Kicinski bed429e1ae mt7601u: fix dma from stack address
DMA to variables located on the stack is a bad idea.
For simplicity and to avoid frequent allocations create
a buffer inside the device structure.  Protect this
buffer with vendor_req_mutex.  Don't protect vendor
requests which don't use this buffer.

Jakub Kicinski 8d0123748a mt7601u: don't warn about devices without per-rate power table
We expect EEPROM per-rate power table to be filled with
s6 values and warn user if values are invalid.  However,
there appear to be devices which don't have this section
of EEPROM initialized.  In such case we should ignore
the values and leave the driver power tables set to zero.

Note that vendor driver doesn't care about this case but
mt76x2 skips 0xff per value.  We take mt76x2's approach.

Johannes Berg 30686bf7f5 mac80211: convert HW flags to unsigned long bitmap
As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.

This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.

The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

Jakub Kicinski 2dea58f629 mt7601u: set promiscous mode based on FIF_OTHER_BSS
Most drivers use FIF_OTHER_BSS to set promiscous mode.  Let us
follow their lead even though it doesn't match exactly the HW
filter flags.

Jakub Kicinski 9a15b57e9a mt7601u: don't cleanup device second time after .resume()
Make sure .disconnect() doesn't cleanup the device if
.resume() failed.  This may happen when device is removed
during suspend.

Jakub Kicinski 2af6d21fce mt7601u: watch out for invalid-length frames
Users of older Ralink devices report that received frames
sometimes have zero length.  Watch out for that.

Jakub Kicinski c869f77d6a add mt7601u driver
Add support for the simplest of MediaTek Wi-Fi devices - MT7601U.
It is a single stream bgn chip with no bells or whistles.
This driver is partially based on Felix's mt76 but IMHO it doesn't
make sense to merge the two right now because MT7601U is a design
somewhere between old Ralink devices and new Mediatek chips.  There
wouldn't be all that much code sharing with the devices mt76 supports.
Situation may obviously change when someone decides to extend m76 with
support for the more recent USB dongles.

The driver supports only station mode.  I'm hoping to add AP support
when time allows.

This driver sat on GitHub for quite a while and got some testing there:
