Re: Possible transmit/stats problem in igb driver.

Wondering if this can happen if somehow the mbuf->m_len is not correct(e.g., 0) and thus causing the dma to fail silently. The only way this is happening if the arp request is larger than 64 bytes and the arp response code is reusing the packet to send a 64 byte response. Thanks, -Sreekanth

That's an interesting theory, you could add a check into the tx path looking for a zero m_len and see, seems unlikely though :) Jack On Fri, Jun 3, 2016 at 1:15 PM, Sreekanth Rupavatharam wrote: > Wondering if this can happen if somehow the mbuf->m_len is not > correct(e.g., 0) and thus causi
