#     uapi: net: ipv6: Replace fake flex-array with flex-array member
#     
#     Zero-length arrays as fake flexible arrays are deprecated and we are
#     moving towards adopting C99 flexible-array members instead.
#     
#     Address the following warning found with GCC-13 and
#     -fstrict-flex-arrays=3 enabled:
#     net/ipv6/exthdrs.c: In function ‘fl6_update_dst’:
#     net/ipv6/exthdrs.c:1393:28: warning: array subscript 0 is outside array bounds of ‘struct in6_addr[0]’ [-Warray-bounds=]
#      1393 |                 fl6->daddr = *((struct rt0_hdr *)opt->srcrt)->addr;
#           |                 ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#     This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
#     routines on memcpy() and help us make progress towards globally
#     enabling -fstrict-flex-arrays=3 [1].
