From 2465665b73ac2f688af945b1ed510752afa816a4 Mon Sep 17 00:00:00 2001 From: David Saada Date: Tue, 15 Jan 2008 10:40:24 +0200 Subject: [PATCH] QE UEC: Extend number of supported UECs to 4 This patch extends the number of supported UECs to 4. Note that the problem of QE thread resources exhaustion is resolved by setting the correct number of QE threads according to Ethernet type (GBE or FE).
