batman-adv: mark a local client as isolated when needed
A client sending packets which mark matches the value
configured via sysfs has to be identified as isolated using
the TT_CLIENT_ISOLA flag.
The match is mask based, meaning that only bits set in the
mask are compared with those in the mark value.
If the configured mask is equal to 0 no operation is
performed.
Such flag is then advertised within the classic client
announcement mechanism.
