[ovs-discuss] Open vSwitch, WLAN and bonding

[kk yap]

Hi,

You can overwrite the mac address of the wireless interface to all
packet to go through.  Most cards allow you to do it, though the USB
and PCMCIA ones sometimes refuse to change their mac address.  This
problem exists when the interface is in managed mode.  If it is in
master mode, I do not think this is an issue.

Just my two cents.

Regards
KK
