Acceleration for virtual bridged hosts

摘要

An approach is provided in which a hardware accelerated bridge executing on a network adapter receives an ingress data packet. The data packet includes a destination MAC address that corresponds to a virtual machine, which interfaces to a software bridge executing on a hypervisor. The hardware accelerated bridge identifies a software bridge table entry that includes the destination MAC address and a virtual function identifier, which identifies a virtual function corresponding to the software bridge. In turn, the hardware accelerated bridge sends the data packet from the hardware accelerated bridge to the software bridge through the identified virtual function.

1. A method comprising:
receiving an ingress data packet at a hardware accelerated bridge executing on a network adapter, the ingress data packet including a destination MAC address that corresponds to a virtual machine that interfaces with a software bridge executing on a hypervisor; identifying, by the hardware accelerated bridge, a software bridge table entry that includes the destination MAC address and a virtual function identifier that identifies a virtual function that corresponds to the software bridge; and sending the data packet from the hardware accelerated bridge to the software bridge using the identified virtual function.
