[PATCH v3] net: stmmac: allocate separate page for buffer

[Furong Xu]

Hi Suraj,

Thanks for this fix.

I tested your patch on XGMAC 3.20a, all goes well, except a performance
drop of ~10%
Like Jakub Kicinski said in V2, this involves more dma_map() and does add
overhead :-/

I might have a better fix for this, I will send to review and CC it to you.

Thanks.
