+Subject: [PATCH] kni: fix build with kernel 4.11
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+compile error:
+.../build/build/lib/librte_eal/linuxapp/kni/kni_net.c:124:6:
+error: implicit declaration of function ‘signal_pending’
+[-Werror=implicit-function-declaration]
+  if (signal_pending(current) || ret_val <= 0) {
+      ^~~~~~~~~~~~~~
+
+Linux 4.11 moves signal function declarations to its own header file:
+Linux: 174cd4b1e5fb ("sched/headers: Prepare to move signal wakeup &
+sigpending methods from <linux/sched.h> into <linux/sched/signal.h>")
+
+Use new header file "linux/sched/signal.h" to fix the build error.

+
+build error:
+.../lib/librte_eal/linuxapp/kni/igb_main.c:1034:10:
+error: implicit declaration of function ‘pci_enable_msix’
+    err = pci_enable_msix(pdev,
+              ^~~~~~~~~~~~~~~
+
+This build error observed when CONFIG_RTE_KNI_KMOD_ETHTOOL config option
+enabled.
+
+Following Linux commit removes the pci_enable_msix()
+Linux: 4244de1c64de ("PCI: remove pci_enable_msix")
+
+Switch to pci_enable_msix_range() for kernel > 4.8 since current Linux
+igb driver uses this function.
