Hello all,
My laptop have re0 and iwlwifi0 network cards with only re0 at use.
vm-bhyve sets it to ifconfig bellow.
I suspect that re0 being in promiscous mode, it will originate some network
problems with backup programs like restic when reading too much files
(restic check --read-data) and to fix this issue I turn off vm-bhyve
network setting.
Is it possible to have a card just to be in use by bhyve, e.g. usb external
ethernet dongle or even laptop wifi card?
Thanks,
