No network on resume from sleep

Hi all,

Ran into this problem after the latest update.
I have a SolarFlare SF7200 NIC that doesn't come back up from S3 state.
The only way to bring it back is to run networkctl reconfigure br1.

dmesg has this to say:

[40230.418978] ACPI: Waking up from system sleep state S3
[40230.487463] sfc 0000:01:00.0 enp1s0f0np0: MC reboot detected
[40230.487465] sfc 0000:01:00.1 enp1s0f1np1: MC reboot detected
[40231.510289] sfc 0000:01:00.0 enp1s0f0np0: link up at 10000Mbps full-duplex (MTU 1500)
[40231.510344] sfc 0000:01:00.1 enp1s0f1np1: resetting (RECOVER_OR_ALL)
[40231.520431] sfc 0000:01:00.0 enp1s0f0np0: resetting (RECOVER_OR_ALL)

systemctl status br1:

Aug 26 06:22:22 arch systemd-networkd[338]: br1: Reset carrier
Aug 26 06:22:22 arch systemd-networkd[338]: br1: No static address is stored.

[Network]

I'm running 5.8.3-arch1-1 kernel and until the last update everything has been working w/o issues.

Would appreciate any input.

Looks like the same issue as here:

A bug in systemd, workaround is to add IgnoreCarrierLoss=true to the network config

That did the trick. Thanks!
