The number of queues that are configured for a VSI depends on the number of TCs that are enabled for the VSI at VSI setup/creation time. But, the total number of queues that are configured for a VSI may change based on change in the total number of TCs enabled as a result of change in DCB configuration based on DCBX. Hence, it is required for the queue vectors to be redistributed when the total queues that are configured for a given VSI changes. Without redistributing the vectors the queues that are configured for the newly enabled TCs may not be able to do any Tx/Rx.

VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty Signed-off-by: David S.

It is possible that the Management Engine might have locked a number of SHRA and not allowed a new address to be written to the requested register. Add a function to determine the number of unlocked SHRA registers. Then determine if the number of registers available is sufficient for our needs, if not then return -ENOMEM so that UNICAST PROMISC mode is activated. Since the method by which ME claims SHRA registers is non-deterministic, also add a return value to the function attempting to write an address to a SHRA, and return a -E1000_ERR_CONFIG if the write fails. The error will be passed up the function chain and allow the driver to also set UNICAST PROMISC when this happens.

The API changes minor numbers when things get added to the API, but no existing structs or calls are changed. The driver has the option of warning that the minor numbers don't match.

To account for this the driver called identify_sfp in ixgbe_get_settings to make sure the data is correct. However when there is no SFP+ module in the cage the driver waits for the I2C reads to time out which can take more than a second and will cause issues with tools (like net-snmp) that may poll for that information. This patch resolves the issue by identifying interfaces with no PHY type set as SFP capable which allows the driver to detect the SFP module when the interface is brought up. As result of this we can also remove the identify_sfp call from ixgbe_get_settings. v2: remove the 82599 specific check since we have 82598 devices that are SFP capable.

First, it only changed the size of the first ring, and second, changing the ring size would often result in a panic because it would change the count before deallocating resources, causing the driver to either free nonexistent buffers, or leak leftover buffers. Fix this by storing the descriptor count in the adapter structure, and updating the count for each ring each time we allocate them. This ensures that we always free the right size ring, and always end up with the requested count when the device is (re)opened.

This fixes the assumptions and allows the kernel to operate as efficiently as possible with both SENDFILE and SEND. In addition, the hardware limit of data contained in a descriptor is changed to the next power of two below where it currently is in order to align to a power of two value, preventing a single byte of data in a descriptor.

Also fix the output to filter read command accordingly.
