Yu Watanabe 7fddb9704f dhcp4: stop client before updating MAC address 2022-08-06 04:53:36 +09:00
Yu Watanabe e33232d405 network: also check SR-IOV PF port and other VF ports before configuring 
When a PF port becomes down (this can happens e.g. the PF port is joining
a bond interface), some drivers make its VF ports also become down, and
may cause failures in configuring VF ports.

Similary, when a VF port become down, some drivers make its PF port and
other VF ports down.

Let's configure SR-IOV ports (both PF and VFs) after all link-layer
settings of all ports being applied.

Fixes #23315.

Yu Watanabe b05e52000b network: do not silently stop to process configuration on activation failure 
Previously, if activation failed, link did not enter the failed state,
but still Link.activated flag not set. Hence, nothing processed even if
the interface is manually brought up later.

Partially fixes #23649.

Yu Watanabe 50ee1fec3a network: dhcp6: re-introduce RapidCommit= setting 
Previous implementation of disabling rapid commit was broken, and
dropped by 308d01f3c4.

Let's re-introduce the option in the correct way, as some servers seem
to return borked message when the solicit message contain the rapid
commit option.

Closes #24065.
