[E1000-devel] IGB/IXGBE/MTA setup

Hi All The MTA table which filters the multicast traffic in 82575/82599 devices are configured differently in IGB/IXGBE driver respectively even though the functionality is same. I would like to know from you if you have seen the same behavior. Scenario: On receiving VF_SET_MULTICAST message f

[E1000-devel] [PATCH v2 1/8] e1000e: Fix TSO with non-accelerated vlans

This device claims TSO support for vlans. It also allows a user to control vlan acceleration offloading. As such, it is possible to turn off vlan acceleration and configure a vlan which will continue to support TSO. In such situation the packet passed down the the device will contain a vlan hea

I've recently ran across something rather interesting when testing vlans from inside VMs. In some scenarios I was getting awfull thruput. Some debugging uncovered a very scary packet corruption. I was seeing packets that had original TSO length as IP total length and their ip checksum was 0. Thi
