test/tft_test: Update filter test suite
The “IPv4 local address type” filter should be 9 bytes since it includes not only the ip address, but also its subnet mask. Quoting from 3GPP TS 24.008 10.5.6.12: """ For "IPv4 remote address type", the packet filter component value field shall be encoded as a sequence of a four octet IPv4 address field and a four octet IPv4 address mask field. The IPv4 address field shall be transmitted first. For "IPv4 local address type", the packet filter component value field shall be encoded as defined for "IPv4 remote address type". """ Same for the ToS which also includes a 1 byte mask value
