From: Adrian Chadd To: "freebsd-arch@freebsd.org" , FreeBSD Net Content-Type: text/plain; charset=UTF-8 X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 15 Jul 2014 22:52:43 -0000 hiya, How many queues does the ixgbe and igb hardware support? The documentation reflects many more transmit and receive queues than the 8 currently auto-configured. For RSS configuration I'd like to expand it out to the 16 that I _think_ the hardware supports, but I'd like some confirmation that the documentation mostly reflects the reality out there and I wouldn't be breaking things on other peoples obscure/onboard/laptop/etc intel platforms. Thanks! -a
