Hi all.

I've tried today to enable the PPP Synchronous mode for my PPPoE
connection , and ifconfig reports a very strange thing:

Look at the ppp0 section , and look at the RX packets area , the
corrupted packages are MORE than the correct packages !! With async mode
this doesn't happen . 
Someone have said me that It could be a kernel bug , is this possible? 

During the connection I don't see any problem , all runs perfectly .

Thank you for your attention :
