From bed429e1ae8b7ee207e01f3aa60dcc0d06a8ed4d Mon Sep 17 00:00:00 2001

Subject: 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.

Subject: mt7601u: fix tx status reporting contexts
mac80211 requires that rx path does not run concurrently with
tx status reporting. Since rx path is run in driver tasklet,
tx status cannot be reported directly from interrupt context
(there would be no way to lock it out).
Add tasklet for tx and move all possible code from irq handler
there.
Note: tx tasklet is needed because workqueue is queued very
rarely and that kills TCP performance.
