This value reports how many outbound buffers are queued waiting to be moved from global memory into local memory, a required step before the LANCE can transmit them. An administrator uses a rising value here to identify a bottleneck in the global-to-local buffer transfer stage of the outbound Ethernet pipeline, distinct from the LANCE's own transmit wait queue. For example, if this queue backs up while cntdot3LanceTxWaitQ stays low, the delay is happening before the data even reaches local memory, pointing at the DMA transfer rather than the transmitter.
