[pve-devel] [PATCH v2 1/2] isisd: fix bit flag collision in options field

[Gabriel Goller]

Resolve conflict between F_ISIS_UNIT_TEST and ISIS_OPT_DUMMY_AS_LOOPBACK
which were both using the same bit value (0x01). This collision caused
unit test mode to be unintentionally enabled when DUMMY_AS_LOOPBACK was set.

Link: https://github.com/FRRouting/frr/pull/18377
Fixes: ecf591e ("frr: add the dummy_as_loopback patch series, enable it by default")
