Looks like my ISP allows both PPPoE and PPPoA. 
After some superficial googling it looks like PPPoE is preferred over
ethernet modems and PPPoA over USB ones... Is it true?

By the way what I need to do is to enable CONFIG_ATM and
CONFIG_PPPOATM in the kernel and reemerge ppp with the "atm" USE flag.

Then I need to change " plugins_ppp1=( "pppoe") " into " plugins_ppp1=( 
"pppoa vc-encaps") " in my /etc/conf.d/net.

Is that all I need to have PPPoA working?
