Subject: [PATCH] brcmfmac: increase message buffer size for control packets
Git-commit: fc4aa125974d4401084eb0f4affdb92e9b75f1df
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430
In wifi firmware, max length of IOCTL/IOVAR buffer size is 8192.
Increase the message buffer max size same as wifi firmware for control
packets so return buffers can come back.
