Subject: [dpdk-dev] [PATCH 1/4] igb_uio: compatible with upstream longterm kernel and RHEL
Date: Wed, 10 Dec 2014 11:33:00 +0800
Message-ID: <1418182383-5744-2-git-send-email-jmiao@redhat.com> (raw)
In-Reply-To: <1418182383-5744-1-git-send-email-jmiao@redhat.com>

Function pci_num_vf() is introduced from upstream linux-2.6.34. So
this patch make compatible with longterm kernel linux-2.6.32.63.

For RHEL, function pci_num_vf() begins from RHEL5 update9. And
it is stub-defined when CONFIG_PCI_IOV is not enabled.

So dropped the CONFIG_PCI_IOV checking of commit 11ba0426.

For other distro like RHEL behaved to pci_num_vf(), we could simply
append following condition macro:
(!(defined(OTHER_RELEASE_CODE) && \
 OTHER_RELEASE_CODE >= OTHER_RELEASE_VERSION(X, Y)))
