Randall Stewart 9518a2a361 If a mbuf is split across two pages, we ... have code that detects this and makes two transmit descriptors. However its possible that the algorithm detects when the second page is not used (when the data aligns perfectly to the bottom of the page). This caused a 0 len descriptor to be added which locks up the rge device. Skip such things with a continue. JC provided this patch...
