Subject: eal: fix build with Xen dom0 enabled
X-Git-Tag: spdx-start~7907
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5142945b3a72b523bb1ab664c4049b5168c0f7e3;p=dpdk.git

eal: fix build with Xen dom0 enabled

There is a new function in the EAL API for internal use.
It has neither a proper prefix nor a .map export:
libethdev.so: undefined reference to `is_xen_dom0_supported'

Fixes: 719dbebceb81 ("xen: allow determining DOM0 at runtime")
