Subject: [dpdk-dev] [PATCH] igb_uio: fix build for longterm kernel 2.6.32.63
Date: Thu, 30 Oct 2014 16:18:24 +0800
Message-ID: <1414657104-16141-1-git-send-email-jmiao@redhat.com> (raw)

There is a logical error in igb_uio/compat.h when define pci_num_vf().
Only CONFIG_PCI_IOV enabled, this function could be defined.

This patch fix the following error for linux-2.6.32.63:
CC [M]  /root/dpdk-source/build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.o
/root/dpdk-source/build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c: In function ‘show_max_vfs’:
/root/dpdk-source/build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c:75: error: implicit declaration of function ‘pci_num_vf’
