Subject: [PATCH] brcmfmac: add credit numbers updating support

The credit numbers are static and tunable per chip in firmware side.
However the credit number may be changed that is based on packet pool
length and will send BRCMF_E_FIFO_CREDIT_MAP event to notify host driver
updates the credit numbers during interface up.
The purpose of this patch is making host driver has ability of updating
the credit numbers when receiving the BRCMF_E_FIFO_CREDIT_MAP event.

Subject: [PATCH] brcmfmac: enable frameburst mode in default firmware setting

The frameburst feature can enable per-packet framebursting in firmware
side and get higher TX throughput in High Throughput(HT) mode. To enhance
TX throughput, we enable frameburst mode in default firmware setting.

Subject: [PATCH] brcmfmac: handle compressed tx status signal

Firmware inform the driver about tx status by normal tx status signal
or compressed tx status signal. This patch adds support to handle the
compressed tx status signal.
