Now we have struct flowi4, flowi6, and flowidn for each address family. And struct flowi is just a union of them all.

2011-03-12ixgbe: DCB, PFC not cleared until reset occursJohn Fastabend2-51/+47
The PFC configuration is not cleared until the device is reset. This has not been a problem because setting DCB attributes forced a hardware reset. Now that we no longer require this reset to occur PFC remains configured even after being disabled until the device is reset. This removes a goto in the PFC hardware set routines for 82598 and 82599 devices that was short circuiting the clear.

2011-03-12ixgbe: add support for VF Transmit rate limit using iproute2Lior Levy5-2/+93
Implemented ixgbe_ndo_set_vf_bw function which is being used by iproute2 tool. In addition, updated ixgbe_ndo_get_vf_config function to show the actual rate limit to the user. The rate limitation can be configured only when the link is up and the link speed is 10Gb. The rate limit value can be 0 or ranged between 11 and actual link speed measured in Mbps. A value of '0' disables the rate limit for this specific VF. iproute2 usage will be 'ip link set ethX vf Y rate Z'. After the command is made, the rate will be changed instantly. To view the current rate limit, use 'ip link show ethX'. The rates will be zeroed only upon driver reload or a link speed change. This feature is being supported by 82599 and X540 devices.

2011-03-12ixgbe: remove timer reset to 0 on timeoutEmil Tantilov1-6/+0
The VF mailbox polling for acks and messages would reset the timer to zero on a timeout. Under heavy load a timeout may actually occur without being the result of an error and when this occurs it is not practical to perform a full VF driver reset on every message timeout. Instead, just return an error (which is already done) and the VF driver will have an opportunity to retry the operation.

2011-03-12ixgbe: DCB during ifup use correct CEE or IEEE modeJohn Fastabend1-10/+20
DCB settings are cleared in the hardware across link events during ifup ixgbe reprograms the hardware for DCB if it is enabled. Now that we have two modes CEE or IEEE we need to use the correct set of configuration data. This patch checks the dcbx_cap bits and then enables the device in the correct mode.

2011-03-12ixgbe: IEEE 802.1Qaz, implement priority assignment tableJohn Fastabend5-19/+36
This patch adds support to use the priority assignment table in the ieee_ets structure to map priorities to traffic classes. Previously ixgbe only supported a 1:1 mapping. Now we can enable and disable hardware DCB support when multiple traffic classes are actually being used. This allows the default case all priorities mapped to traffic class 0 to work in normal hardware mode and utilize the full packet buffer. This patch does not address putting the hardware in 4TC mode so packet buffer space may be underutilized in this case. A follow up patch can address this optimization. But at least we have the hooks to do this now. Also CEE will behave as it always has and map priorities 1:1 with traffic classes.

2011-03-12ixgbe: DCB, use multiple Tx rings per traffic classJohn Fastabend3-168/+182
This enables multiple {Tx|Rx} rings per traffic class while in DCB mode. In order to get this working as expected the tc_to_tx net device mapping is configured as well as the prio_tc_map. skb priorities are mapped across a range of queue pairs to get a distribution per traffic class. The maximum number of queue pairs used while in DCB mode is capped at 64. The hardware max is actually 128 queues but 64 is sufficient for now and allocating more seemed a bit excessive. It is easy enough to increase the cap later if need be. To get the 802.1Q priority tags inserted correctly ixgbe was previously using the skb queue_mapping field to directly set the 802.1Q priority. This no longer works because we have removed the 1:1 mapping between queues and traffic class. Each ring is aligned with an 802.1Qaz traffic class so here we add an extra field to the ring struct to identify the 802.1Q traffic class. This uses an extra byte of the ixgbe_ring struct fortunately there was a 2byte hole, struct ixgbe_ring { void * desc; /* 0 8 */ struct device * dev; /* 8 8 */ struct net_device * netdev; /* 16 8 */ union { struct ixgbe_tx_buffer * tx_buffer_info; /* 8 */ struct ixgbe_rx_buffer * rx_buffer_info; /* 8 */ }; /* 24 8 */ long unsigned int state; /* 32 8 */ u8 atr_sample_rate; /* 40 1 */ u8 atr_count; /* 41 1 */ u16 count; /* 42 2 */ u16 rx_buf_len; /* 44 2 */ u16 next_to_use; /* 46 2 */ u16 next_to_clean; /* 48 2 */ u8 queue_index; /* 50 1 */ u8 reg_idx; /* 51 1 */ u16 work_limit; /* 52 2 */ /* XXX 2 bytes hole, try to pack */ u8 * tail; /* 56 8 */ /* --- cacheline 1 boundary (64 bytes) --- */ Now we can set the VLAN priority directly and it will be correct. User space can indicate the 802.1Qaz priority using the SO_PRIORITY setsocket() option and QOS layer will steer the skb to the correct rings. Additionally using the multiq qdisc with a queue_mapping action works as well.

2011-03-12ixgbe: DCB, implement capabilities flagsJohn Fastabend3-36/+95
This implements dcbnl get and set capabilities ops. The devices supported by ixgbe can be configured to run in IEEE or CEE modes but not both. With the DCBX set capabilities bit we add an explicit signal that must be used to toggle between these modes. This patch adds logic to fail the CEE command set_hw_all() which programs the device with a CEE configuration if the CEE caps bit is not set. Similarly, IEEE set commands will fail if the IEEE caps bit is not set. We allow most CEE config set commands to occur because they do not touch the hardware until set_hw_all() is called. The one exception to the above is the {set|get}app routines. These must always be protected by caps bits to ensure side effects do not corrupt the current configured mode. By requiring the caps bit to be set correctly we can maintain a consistent configuration in the hardware for CEE or IEEE modes and prevent partial hardware configurations that may occur if user space does not send a complete IEEE or CEE configurations. It is expected that user space will signal a DCBX mode before programming device.
