Its sole purpose is to reinitialize hardware for real watchdog
timeouts. It's not fix for general watchdog timeouts. As I said other
mails, the fake watchdog timeout(losing Tx interrupts) for hardwares
with Tx interrupt moderation capability could be normal thing. So I
just want to know bge(4) also has the same feature(bug).

using watchdog?
