Subject: be2net: Bug fix to avoid soft lockup in loopback test.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d7b901418250f00eaaa18f9135d09ba61b72a5bc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

be2net: Bug fix to avoid soft lockup in loopback test.

This change ensures that loopback test command gives up after 4 seconds when
the hardware is not responsive. This could happen if the ports are connected
properly in loopback mode.
