| Subject: i40e: Able to add up to 16 MAC filters on an untrusted VF |
| |
| [ Upstream commit 06b6e2a2333eb3581567a7ac43ca465ef45f4daa ] |
| |
| This patch fixes the problem with the driver being able to add only 7 |
| multicast MAC address filters instead of 16. The problem is fixed by |
| changing the maximum number of MAC address filters to 16+1+1 (two extra |
| are needed because the driver uses 1 for unicast MAC address and 1 for |
| broadcast). |
