Subject: ixgbe: Move all values that deal with count, next_to_use, next_to_clean to u16
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=63544e9c0055316d0397cb671f2ff99d85c77293;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ixgbe: Move all values that deal with count, next_to_use, next_to_clean to u16

This change updates all values dealing with count, next_to_use, and
next_to_clean so that they stay u16 values.  The advantage of this is that
there is no re-casting of type during the propagation through the stack.
