Hi all.
I've tried today to enable the PPP Synchronous mode for my PPPoE connection , and ifconfig reports a very strange thing:
melchior:/home/melchior# ifconfig eth0 Link encap:Ethernet HWaddr 00:40:F4:55:A1:40 inet addr:192.168.254.1 Bcast:192.168.254.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:774 errors:0 dropped:0 overruns:0 frame:0 TX packets:579 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:362290 (353.7 KiB) TX bytes:51218 (50.0 KiB) Interrupt:19 Base address:0x1f00

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 :
