When needed (i.e. when the packet goes to a non-access port), yes.

Okay, works for me principally. If it's later found insufficient,
relaxing push_vlan and pop_vlan to work also for L3 frames is still
easily possible without breaking compatibility.
Out of curiosity (and without looking at the user space patchset), what
will the pushed Ethernet header contain? E.g., consider the following
scenario: two GRE ports, both set as access ports with the same tag,
and a mirror port mirroring everything. Now an IP packet without inner
Ethernet header is received on one of the GRE interfaces.
Will the packet be output to the second GRE port? Will it be sent out
without the inner Ethernet header? Are custom rules necessary, or will
NORMAL take care of this? What will be sent to the mirror port?
Thanks!
Jiri
