| | | | | | | | | | | | | | skb_fill_rx_data() pulls 64 byte of data in skb->data Its too much for TCP (with no options) on IPv4, as total size of headers is 14 + 40 = 54 This means tcp stack and splice() are suboptimal, since tcp payload is in part in tcp->data, and in part in skb frag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Calling pci_disable_sriov() while VFs are assigned to VMs causes kernel panic. This patch uses PCI_DEV_FLAGS_ASSIGNED bit state of the VF's pci_dev to avoid this. Also, the unconditional function reset cmd issued on a PF probe can delete the VF configuration for the previously enabled VFs.
