Just in case, the hash (as well as version) of firmware which I
downloaded from intel-aero and I use to capture is the following:
$ sha256sum /lib/firmware/shisp_2401a0_v21.bin
e89359f4e4934c410c83d525e283f34c5fcce9cb5caa75ad8a32d66d3842d95c /lib/firmware/shisp_2401a0_v21.bin
$ strings /lib/firmware/shisp_2401a0_v21.bin | grep 2015
irci_stable_candrpv_0415_20150521_0458
