Subject: [build] Drag in Xen and Hyper-V support via network device drivers
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7a2817bbd7c0ae4f63044d2e3b9f01c3bacbd1f9;p=thirdparty%2Fipxe.git

[build] Drag in Xen and Hyper-V support via network device drivers

Include Xen and Hyper-V support in the all-drivers build by dragging
in the netfront and netvsc drivers, since these are the functional
drivers that provide network interfaces.
