From: Cunming Liang Date: Mon, 20 Jul 2015 03:02:23 +0000 (+0800) Subject: eal/linux: fix link status interrupt with uio_pci_generic X-Git-Tag: spdx-start~8617 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5cbae268decd7dce54b8fc623b6d58db16375047;p=dpdk.git eal/linux: fix link status interrupt with uio_pci_generic The intr handle type(RTE_INTR_HANDLE_UIO_INTX) was introduced by UIO pci generic. When turning on the lsc interrupt, it complains fd read error. The patch uses the correct read size in the case of RTE_INTR_HANDLE_UIO_INTX.
