<pre class="bz_comment_text">Following de5da9d16430 ("net/ice: support double VLAN"), "single" vlan
stripping is broken with net/ice devices.
This was reported on the users@ mailing list.

Basically, vlan does not get stripped and the vlan tci is not put in mbuf
metadata:
With v24.03-rc2:
# ./build/app/dpdk-testpmd -a 0000:04:00.0 -- --enable-hw-vlan-strip -i
...
ice_load_pkg_type(): Active package is: 1.3.30.0, ICE OS Default
Package (double VLAN mode)
...
testpmd> set verbose 1
Change verbose level from 0 to 1
testpmd> start
