Hi,
I have one questions:
Is it right, that if my ethernet driver returns an error after a write()
call, for example its sendqueue is full, the tcp-layer will recognize this
first, when a ACK_TIME_OUT occurs? Shouldn't the stack instead keep the
data in the unsent-queue return the error to the application and wait until
the driver has enough space for the packet? Or even better the driver
calls tcp_output after each TX Confirmation.
