Minimize the need for users to have to set module parameters to get good performance. The following two parameters are changed: - rcvhdrcnt to twice the rcvegrcnt - pcie_caps=0x51 The rcvhdrcnt at twice the egrcount allows the preemptive NAK code during reception to function in 100% of the cases rather than a sender jiffies-based timeout. The pcie_caps default of 0x51 will set the proposed MaxPayload and MaxReceiveReqest to 256 and 4096 respectively. The capabilities on the root complex will be used to limit those values.
