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).
