This breaks NetBSD 5.1/arc networking. This seems to revert the following commit and change the function return value. commit 409b52bfe199d8106dadf7c5ff3d88d2228e89b5 Author: Hervé Poussineau <hpoussin@reactos.org> Date: Wed Jun 3 22:45:48 2015 +0200 net/dp8393x: correctly reset in_use field Don't write more than the field width, which is always 16 bit.

address_space_rw() access size must be multiplied by width. dp8393x_receive() must return the number of bytes read, not the length of the last memory access. Signed-off-by: Laurent Vivier <laurent@vivier.eu> --- hw/net/dp8393x.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-)
