liquidio: xmit_more support Defer ringing the Tx doorbell if skb->xmit_more is set unless the Tx queue is full or stopped. To keep latency low, use a deferral limit of 8 packets. We chose 8 because Octeon can fetch at most 8 packets in a single PCI read, and our tests show that 8 results in low latency.

liquidio: fix VF incorrectly indicating that it successfully set its VLAN For security reasons, NIC firmware does not allow VF to set its VLAN if PF set it already. Firmware allows VF to set its VLAN if PF did not set it. After the VF instructs the firmware to set the VLAN, VF always indicates (via return 0) that the operation is successful--even for the times when it isn't. Put in a mechanism for the VF's set VLAN function to receive the firmware response code, then make that function return -EPERM if the firmware forbids the operation. Make that mechanism available for other functions that may, in the future, be interested in receiving the response code from the firmware. That mechanism involves adding new fields to struct octnic_ctrl_pkt, so make all users of struct octnic_ctrl_pkt initialize the struct to zero before using it; otherwise, the mechanism might act on uninitialized garbage.

Add support of Cavium Liquidio ethernet adapters Following patch V8 adds support for Cavium Liquidio pci express based 10Gig ethernet adapters. 1) Consolidated all debug macros to either call dev_* or netdev_* macros directly, feedback from previous patch. 2) Changed soft commands to avoid crash when running in interrupt context. 3) Fixed link status not reflecting correct status when NetworkManager is running. Added MODULE_FIRMWARE declarations. Following were the previous patches. Patch V7: 1) Minor comments from v6 release regarding debug statements. 2) Fix for large multicast lists. 3) Fixed lockup issue if port initialization fails. 4) Enabled MSI by default. https://patchwork.ozlabs.org/patch/464441/ Patch V6: 1) Addressed the uint64 vs u64 issue, feedback from previous patch. 2) Consolidated some receive processing routines. 3) Removed link status polling method. https://patchwork.ozlabs.org/patch/459514/ Patch V5: Based on the feedback from earlier patches with regards to consolidation of common functions like device init, register programming for cn66xx and cn68xx devices. https://patchwork.ozlabs.org/patch/438979/ Patch V4: Following were the changes based on the feedback from earlier patch: 1) Added mmiowb while synchronizing queue updates and other hw interactions. 2) Statistics will now be incremented non-atomically per each ring. liquidio_get_stats will add stats of each ring while reporting the total statistics counts. 3) Modified liquidio_ioctl to return proper return codes. 4) Modified device naming to use standard Ethernet naming. 5) Global function names in the driver will have lio_/liquidio_/octeon_ prefix. 6) Ethtool related changes for: Removed redundant stats and jiffies.
