[U-Boot] [PATCH] net: Use ARRAY_SIZE at appropriate places

[Axel Lin <axel.lin@ingics.com>]

Use ARRAY_SIZE instead of having similar implementation in each drivers.

Hi,
tools/checkpatch.pl shows
total: 2 errors, 12 warnings, 0 checks, 89 lines checked

The errors are:
ERROR: code indent should use tabs where possible

The warnings are something like below:
WARNING: line over 80 characters
WARNING: please, no spaces at the start of a line
WARNING: Avoid CamelCase: <ixEthDBPortDefinitions>

I don't fixup the checkpatch.pl issues because I feel having the patch
as is seems cleaner.

Regards,
Axel
