Subject: rtl8139: Fix behaviour for old kernels.
X-Git-Tag: qemu-xen-4.20.0~37^2~7
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=9e3b9f27658cce308b7f71b19a4ec31749575414;p=qemu-xen.git

rtl8139: Fix behaviour for old kernels.

Old linux kernel rtl8139 drivers (ex. debian 2.1) uses outb to set the rx
mode for RxConfig. Unfortunatelly qemu does not support outb for RxConfig.
