ramips: Use doubletagging to disable ramips_esw vlan by default, it seems more reliable.
Use doubletagging to disable ramips_esw vlan by default, it seems
more reliable.
Daniel Golle found an issue where sometimes (possibly only for
RT3352) the default vlan disable method (clearing en_vlan, untag,
doubletag and putting all ports into vlan 0) doesn't work and the
packets get sent out vlan-tagged with vlan 0.
Instead switch to using the doubletagging method (allow doubletagged
packets, put all ports into vlan 0 with untag enabled) by default.
Unless someone figures out a way to really globally disable vlan for
this switch, this seems like the best (most reliable) option.
I did some tests regarding maximum packet size and did not see any
difference between the two methods, both allow for slightly bigger packets
than the ramips_main.c ethernet driver (ping stops going through
above "ping -s 1472" (1514 bytes), on the switch packets are recv_good until
"ping -s 1490", or about 1532 bytes).
