From: Sucheta Chakraborty Date: Mon, 4 Nov 2013 18:31:29 +0000 (-0500) Subject: qlcnic: Register netdev in FAILED state for 83xx/84xx X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=78ea2d977a11b2435d733628463cf1274cf40531;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git qlcnic: Register netdev in FAILED state for 83xx/84xx o Without failing probe, register netdev when device is in FAILED state. o Device will come up with minimum functionality and allow diagnostics and repair of the adapter.
