From 00dec3065ab816e9e47234a3623010547cb7e487 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Thu, 11 Oct 2018 18:00:03 -0700 Subject: dev: Build most of the networking devices in the NULL_ISA build. The only part of these devices which are incompatible with other ISAs, with the possible exception of endianness transformation, is that the dist_iface implementation refers to ThreadContext methods and that class is heavily tied to the guest ISA. Only those few lines are excluded in a NULL_ISA build.
