qcacld-3.0: Add support for BPF data offload
qcacld-2.0 to qcacld-3.0 propagation
Currently wlan firmware has multiple different packet filters,
offload features such as Magic Pattern filter, MCBC filter,
RA filter and Bitmap pattern filter.
Firmware has to maintain different filter settings and different
source code to compare the filters.
BPF data offload is common architecture for packet filter offload.
Implement BPF data offload in driver.
