ip neigh: allow flush FAILED neighbour entry
|
|
|
cd1737 |
|
|
|
cd1737 |
After upstream commit 5071034e4af7 ('neigh: Really delete an arp/neigh entry
|
|
|
cd1737 |
on "ip neigh delete" or "arp -d"'), we could delete a single FAILED neighbour
|
|
|
cd1737 |
entry now. But `ip neigh flush` still skip the FAILED entry.
|
|
|
cd1737 |
|
|
|
cd1737 |
Move the filter after first round flush so we can flush FAILED entry on fixed
|
|
|
cd1737 |
kernel and also do not keep retrying on old kernel.
