[U-Boot] [RFC Patch] e1000: Fix PCI memory addressing and fix for receive data polling

Hi all,

I had some problem when using your e1000-code on a MIPS target. Attached you will find two fixes which I would like to propose for discussion.

- Fix 1: this has the same reason as in commit f81ecb5d3300bf92d17302d3712f30585c182da9

- Fix 2: has to do with "C Language Operator Precedence". I would say the expression taken by the ! operator has precedence before the & operator. So any bit in rd->status other than E1000_RXD_STAT_DD stops correct detection of data reception. (What i do not know is, if it is possible that any other bit than E1000_RXD_STAT_DD can get active)

Please leave me in CC, because i'm not subscribed to this list.

Thanks a lot for providing u-boot.

Best regards Ralf
