MDK4 is a Wi-Fi testing tool that implements several Denial-of-Service and
beacon-flooding attacks against IEEE 802.11 networks, exploiting
weaknesses in the protocol itself.

%build
# -fcommon still needed (GCC 10+ multiple defs); DLT/MAGIC macros gone from
# libpcap headers; command-line CFLAGS override also drops common.mak's
# libnl/API defines, so carry them here
