Hi, Alexey.

 /* Tx timeout interval (millisecs) */
-static int watchdog = 400;
+static int watchdog = 5000;

Five second transmit timeout.  Why is this?

And why do we do this:


each time we send a frame with hardware checksum?  This is the
transmit path, not the receive path.  It seems we're abusing
some ppp-related stats here.  What's up?
