Replace a call to the driver-specific get_da function with
ieee80211_get_DA from ieee80211.h.

trivia:

As both of the addresses returned are minimum __aligned(2),
these memcmp uses could be ether_addr_equal

Look for ETH_ALEN

$ git grep ETH_ALEN drivers/staging/r8188eu/

Perhaps see if the memcpy/memcmp uses with ETH_ALEN could be
converted to ether_addr_copy/ether_addr_equal or any of the
other is_<foo>_ether_addr calls.

Thanks, I'll fix this in a separate patch and keep this pattern in mind
for other parts of the code.
