Currently iavf unconditionally applies MAC address change requests. This brings the VF in a state where it is no longer able to pass traffic if the PF rejects a MAC filter change for the VF. A typical scenario for a rejected MAC filter is for an untrusted VF to request to change the MAC address when an administratively set MAC is present. To keep iavf working in this scenario the MAC filter handling in iavf needs to act on the PF reply regarding the MAC filter change. In the case of an ack the new MAC address gets set, whereas in the case of a nack the previous MAC address needs to stay in place.

The "Negotiated" string in i40e_print_link_message() function was missed. This string has been added to the dmesg and small refactoring done removing common substrings and unifying link status message format. Without this patch it was not clear that FEC is related to negotiated FEC.

While testing VF spawn/destroy the following panic occurred.

To avoid this the call to i40e_sync_vsi_filters() in i40e_sync_filters_subtask() needs to be guarded by __I40E_VF_DISABLE, which is also used by i40e_free_vfs(). Note: put the __I40E_VF_DISABLE check after the __I40E_MACVLAN_SYNC_PENDING check as the latter is more likely to trigger.

In ixgbe_configure_clsu32(), 'jump', 'input', and 'mask' are allocated through kzalloc() respectively in a for loop body. Then, ixgbe_clsu32_build_input() is invoked to build the input. If this process fails, next iteration of the for loop will be executed. However, the allocated 'jump', 'input', and 'mask' are not deallocated on this execution path, leading to memory leaks.

Similar to the 'reset_dev_on_drv_probe' devlink parameter, it is useful to have an unknown value which can be used by drivers to report that the hardware value isn't recognized or is otherwise invalid instead of failing the operation.

Currently frame registrations are not purged, even when changing the interface type. This can lead to potentially weird situations where frames possibly not allowed on a given interface type remain registered due to the type switching happening after registration. The kernel currently relies on userspace apps to actually purge the registrations themselves, this is not something that the kernel should rely on. Add a call to cfg80211_mlme_purge_registrations() to forcefully remove any registrations left over prior to switching the iftype.

Currently when hns3 driver configures the tm shaper to limit bandwidth below 20Mbit using the parameters calculated by hclge_shaper_para_calc(), the actual bandwidth limited by tm hardware module is not accurate enough, for example, 1.28 Mbit when the user is configuring 1 Mbit. This patch adjusts the ir_calc to be closer to ir, and always calculate the ir_b parameter when user is configuring a small bandwidth. Also, removes an unnecessary parenthesis when calculating denominator.

When we expire an inactive station, try to send it a deauth. This helps if it's actually still around, and just has issues with beacon distribution (or we do), and it will not also remove us. Then, if we have shared state, this may not be reset properly, causing problems; for example, we saw a case where aggregation sessions weren't removed properly (due to the TX start being offloaded to firmware and it relying on deauth for stop), causing a lot of traffic to get lost due to the SN reset after remove/add of the peer.
