Hello,
I have setup a trunk combination on my Pi 4 to aggregate the ethernet
port (bse0) with the wireless port (bwfm0) using the examples in the
documentation:
$ cat /etc/hostname.bse0
up
$ cat /etc/hostname.bwfm0
join "MyAp" wpakey "blablabla"
up
$ cat /etc/hostname.trunk0
trunkproto failover trunkport bse0
trunkport bwfm0
inet autoconf
And with the ethernet cable plugged in, I have networking through it:
$ ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 32768
index 3 priority 0 llprio 3
groups: lo
inet6 ::1 prefixlen 128

But as soon as I remove the ethernet cable, I get no networking with
the wireless access point

Do I miss something?
Nothing particular in dmesg, it's running 7.1 aarch64.
I’ve tested the bwfm0 interface without being put in trunk, it works
fine.
