It really means that the send queue in the driver is full and no further packets can be added to it until it drains soemwhat. The message indicates that, for some reason, the driver can't send out any packets on the wire. For some reason most people think that this message means they've run out of mbufs. Examination of the source would quickly disabuse them of this idea. --- Gary Jennejohn / garyj[at]jennejohn.org gj[at]freebsd.org gj[at]denx.de
