Second set of three with the end goal of enabling IPv6 gateways with IPv4
routes.
This set moves:
- the ipv4 tracepoint to take a fib_nh_common and updates it to handle
a v6 gateway.
- consolidates route notifications to use the same fill functions
for both ipv4 and ipv6
v3
- comments from Martin:
+ renamed FIB_RES_NH to FIB_RES_NHC
+ removed family check from fib_result_prefsrc
+ in fib_nexthop_info, renamed nexthop arg to nhc and dropped for_ipv4 arg
v2
- dropped patches moving cached routes and exception buckets to
fib_nh_common. The goal is allowing a fib6_nh to be used with an
IPv4 route. The hold up is the need for separate exception buckets -
one for v6 routes and one for v4 routes. When all of the nexthop patches
are in, adding a secondi exception bucket pushes IPv6 fib6_info
allocations over 256 which means fib6_info allocations roll up to 512.
Hence, deferring the patches until some data mining can be done to keep
the allocations at 256.
David Ahern (5):
ipv4: Update fib_table_lookup tracepoint to take common nexthop
ipv4: Add fib_nh_common to fib_result
ipv4: Refactor nexthop attributes in fib_dump_info
ipv4: Change fib_nexthop_info and fib_add_nexthop to take
fib_nh_common
ipv6: Flip to fib_nexthop_info
