2017-04-12ftgmac100: Set default ring sizes to 128 entriesBenjamin Herrenschmidt
I haven't seen any improvement above that size on the machines I've tested with. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-12ftgmac100: Make ring sizes configurable via ethtoolBenjamin Herrenschmidt
We set an arbitrary max at 1024 since we pre-allocate the actual descriptor arrays and skb arrays to the full size to keep the code a bit simpler and avoid allocation failures in the reset task.

2017-04-12ftgmac100: Disable HW checksum generation on AST2400, enable on othersBenjamin Herrenschmidt
We found out that HW checksum generation only works from AST2500 onward. This disables it on AST2400 and removes the "no-hw-checksum" properties in the device-trees. The problem we had wasn't related to NC-SI. Also rework the logic testing for that property so it can be used to disable HW checksum generation and checking regardless of whether NC-SI is used or not in case other variants out there need this.

2017-04-12ftgmac100: Use device "compatible" property, not machine.Benjamin Herrenschmidt
We test for aspeed chips to handle a couple of special cases, but we do that by checking the machine type which isn't right. Instead check the actual device compatible property.

2017-04-10ftgmac100: Cleanup tx queue handlingBenjamin Herrenschmidt
We have a private lock which isn't terribly useful, and we maintain a "tx_pending" counter for information that's already available via a trivial arithmetic operation. Then we unconditionaly wake the queue even when not stopped. Finally our code in tx isn't really safe vs. a concurrent reclaim. The aspeed chips aren't SMP today but I prefer the code being right and future proof. So rip that out and replace it with more "standard" queue handling, currently with a threshold of 1 queue element, which will be increased when we implement fragmented sends.

2017-04-10ftgmac100: Store tx skbs in a separate arrayBenjamin Herrenschmidt
Rather than in the descriptor. The descriptor is mapped non-cachable and rather slow to access. Since to do that we need to keep track of the tx "pointer" we also have no use of all the accesors to manipulate it, just open code it, it's as clear and will help when adding fragmented sends.

Mitch fixes an issue where the client driver (i40iw) was attempting to load on x710 devices (which do not support iWARP), so only register with the client if iWARP is supported. Jake fixes up error messages to better clarify to the user when adding a invalid flow type. Updates the driver to look up the MAC address from eth_get_platform_mac_address() first before checking what the firmware provides. Cleans up code so we are not repeating a duplicate loop, by checking both transmit and receive queues in a single loop. Also cleans up flags never used, so remove the definitions. Alex does cleanup so that we are always updating pf->flags when a change is made to the private flags. Adds support for 3K buffers to the receive path so that we can provide the additional padding needed in the event of NET_IP_ALIGN being non-zero or a cache line being greater than 64. Adds support for build_skb() to i40e/i40evf. Maciej adjusts the scope of the rtnl lock held during reset because it was stopping other PFs from running their reset procedures. Alan reduces code complexity in i40e_detect_recover_hung_queue(). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-08liquidio: fix VF incorrectly indicating that it successfully set its VLANFelix Manlunas
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.
