From 95dd44b4f31eef3cce0f98967635431e10e31c98 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 14 Nov 2014 00:56:19 +0000 Subject: [PATCH] igb: Clean-up page reuse code This patch cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. It also cleans up how we clear the descriptor status bits. Previously they were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a 64 bit field and 64 bit writes can be a bit more expensive on on 32 bit systems. Since we are no longer using the header split feature the upper 32 bits of the address no longer need to be cleared. As a result we can just clear the status bits and leave the length and VLAN fields as-is which should provide more information in debugging.
