From 4b49804158beb14a64418c61eaf927c1aea32a07 Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Fri, 3 Mar 2017 15:22:27 +0000 Subject: [PATCH] sfc: fix IPID endianness in TSOv2 The value we read from the header is in network byte order, whereas EFX_POPULATE_QWORD_* takes values in host byte order (which it then converts to little-endian, as MCDI is little-endian).
