Subject: [PATCH 19/22] fix(fw): when checking tables make sure to check the
|
|
|
47f735 |
actual backend
|
|
|
47f735 |
|
|
|
47f735 |
Calling get_backend_by_ipv() will return nftables if we're using
|
|
|
47f735 |
nftables backend, but we really need to check if iptables, et al. are
|
|
|
47f735 |
available.
