Subject: eal/linux: fix build when VFIO is disabled
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e8a17faa5ebc7067473b4948805753251dc0c2e9;p=dpdk.git

eal/linux: fix build when VFIO is disabled

The header linux/version.h isn't included when CONFIG_RTE_EAL_VFIO
is explicitly disabled. LINUX_VERSION_CODE and KERNEL_VERSION are
therefore undefined, causing the build failure:

  lib/librte_eal/linux/eal/eal.c: In function ‘rte_eal_init’:
  lib/librte_eal/linux/eal/eal.c:1076:32: error: "LINUX_VERSION_CODE" is
    not defined, evaluates to 0 [-Werror=undef]

Fixes: a0dede62a537 ("eal/linux: remove KNI restriction on IOVA")
