From d51019a4daac885ac4dead9d45d3a2a61189d9fd Mon Sep 17 00:00:00 2001 From: PJ Waskiewicz Date: Fri, 13 Mar 2009 22:12:48 +0000 Subject: [PATCH] ixgbe: Fix an accounting problem when the Rx FIFO is full The rx_no_dma_resources counter reported by ethtool -S ethX is not counting correctly. In 82599, the queue mappings for the counters need to be mapped properly, and accounted for properly.
