sharpd: add uSID instruction support to seg6local routes
Seg6local routes can be installed with uSID instruction. > ubuntu2204hwe# sharp install seg6local-routes 1006::1 nexthop-seg6local loop1 uN > ubuntu2204hwe# Ctrl-D > # ip -6 ro show > 1006::1 nhid 28 encap seg6local action End flavors next-csid lblen 32 nflen 16 dev loop1 proto 194 metric 20 pref medium As of today, uA and uN can be displayed with iproute2. The other instructions are not rejected by the kernel, but are not displayed by iproute2. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
