From: Carolyn Wyborny Date: Thu, 1 Oct 2015 18:37:39 +0000 (-0400) Subject: i40e: Fix an incorrect OEM version string X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2efaad86b5cdd0f6d70436fa304a567df8a3cf6c;p=openwrt%2Fstaging%2Fblogic.git i40e: Fix an incorrect OEM version string This patch fixes a problem where the driver output of the OEM version string varied from the other tools. The mask value and the order of operations were incorrect, per the original change request. Without this patch, the version string will appear incorrect from the driver.
