Subject: stmmac: set dirty index out of the loop
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fbc80823a93c57f2310dacfabfea6c76424552b6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

stmmac: set dirty index out of the loop

The dirty index can be updated out of the loop where all the
tx resources are claimed. This will help on performances too.
Also a useless debug printk has been removed from the main loop.
