be2net: do not modify PCI MaxReadReq size
Setting the PCI MRRS to a value of 4096 (overriding the system decided value) had provided perf improvement in TX. But, IBM has provided feedback that on POWER platforms, this value is set by the system firmware, and drivers modifying this value can cause unpredictable results (like EEH errors.) So, backing off this change. On POWER7 platforms most slots, it seems, do get a MRRS of 4096. This patch reverts the following commit: "be2net: Modified PCI MaxReadReq size to 4096 bytes" commit 5a56eb10babbcd7b3796dc3c28c271260aa3608d.
