Subject: [PATCH net-next 09/12] brcmfmac: msgbuf: Increase RX ring sizes to
 1024

From: Hector Martin <marcan@...can.st>

Newer chips used on Apple platforms have a max_rxbufpost greater than
512, which causes warnings when brcmf_msgbuf_rxbuf_data_fill tries to
put more entries in the ring than will fit. Increase the ring sizes
to 1024.
