+Subject: [PATCH 1/7] brcmfmac: reset two D11 cores if chip has two D11 cores
+
+There are two D11 cores in RSDB chips like 4359. We have to reset two
+D11 cores simutaneously before firmware download, or the firmware may
+not be initialized correctly and cause "fw initialized failed" error.

+Set F2 blocksize to 256 bytes and watermark to 0x40 for 4359. Also
+enable and configure F1 MesBusyCtrl. It fixes DMA error while having

+ support MBSS
+
+With RSDB mode, FMAC and firmware are able to create 2 or more AP,
+so we should not set mbss in vif structure if firmware does not
+support MBSS feature.
