What about main and 10x firmware branch?

There is no code changes in firmware. It's a configuration change of
host memory access.

Please change it for main and 10x branch too. Dumping hw1.0 regs with
QCA driver shows DMA burst value set to 1

Looks some old chips have different definitions of DMA burst size. We are discussing internally to change it for 10.4 only because we only tested 10.4. On the other hand we are waiting for HW team to explain the differences.
