From 7563907eb8aad8f15b6a39fa6d863c091d83ef48 Mon Sep 17 00:00:00 2001 From: Michael Barkowski Date: Fri, 13 Apr 2007 01:26:15 -0500 Subject: ucc_geth: Fix interrupt coalescing size and alignment The rx interrupt coalescing table alignment was "guessed" to be 4, but should be 64. The size should be 8 * number of queues + 4. Verified in the MPC8323E manual.
