Subject: [PATCH wireless-next v2 09/12] brcmfmac: msgbuf: Increase RX ring
 sizes to 1024

Precedence: bulk

From: Hector Martin <marcan@marcan.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.
