Re: QCA998X not working at all

[Sebastian Gottschall <s.gottschall@dd-wrt.com>]

the patch subjected with:  ath10k: use pre-allocated DMA buffer in Tx
must be reverted.
it will lead to out of memory when using multiple cards on ipq806x. it 
seems that there isnt enough dma buffer available on this platform
reverting this patch will fix it
