sysctl for `net.ipv4.fib_multipath_hash_policy` appears to not be getting set:
```
trae@cr01a-vyos# show system sysctl
custom net.ipv4.fib_multipath_hash_policy {
value 1
}
custom net.ipv4.tcp_congestion_control {
value vegas
}
custom net.ipv6.fib_multipath_hash_policy {
value 1
}
[edit]
trae@cr01a-vyos# sysctl -a 2>&1 | grep fib
net.ipv4.fib_multipath_hash_policy = 0
net.ipv4.fib_multipath_use_neigh = 0
net.ipv6.fib_multipath_hash_policy = 1
```
If I set it manually it works fine:
```
trae@cr01a-vyos# sudo sysctl -w net.ipv4.fib_multipath_hash_policy=1
net.ipv4.fib_multipath_hash_policy = 1
[edit]
trae@cr01a-vyos# sysctl -a 2>&1 | grep fib
net.ipv4.fib_multipath_hash_policy = 1
net.ipv4.fib_multipath_use_neigh = 0
net.ipv6.fib_multipath_hash_policy = 1
```
Edit: I tested it on another router (same version) and it appears that it works before rebooting, but not after.
