From 1fb9876e9bf895ea4127ff17180f1b2ab37771b6 Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Tue, 22 Mar 2011 22:37:52 +0000 Subject: mlx4_en: using new mlx4 interrupt scheme Each RX ring will have its own interrupt vector, and TX rings will share one (we mostly use polling for TX completions). The vectors are assigned first time device is opened, and its name includes the interface name and ring number. Signed-off-by: Markuze Alex Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.

The same packet steering mechanism would be used both for IB and Ethernet, Both multicasts and unicasts. This commit prepares the general infrastructure for this.
