[U-Boot] [PATCH] net: e1000: Fix packet length conversion

[Miao Yan]

Hi Lian,

2016-01-06 16:41 GMT+08:00 Minghuan Lian <Minghuan.Lian at nxp.com>:
> The length of the receiving packet descriptor is a 16bit integer
> not 32bit. le32_to_cpu should be replaced by le16_to_cpu to
> make the correct conversion. Otherwise, e1000 cannot work on
> some kinds of big-endian platform.
