2019-02-26vmxnet3: RSS supportSteven Luong7-81/+229
Configurable up to 16 RX queues per interface. Default is 1. Change-Id: If9e2beffeb7e7dc8c2264b4db902132b2fea02c1 Signed-off-by: Steven Luong <sluong@cisco.com>
2019-02-26vmxnet3: lro/tso and rx checksumSteven Luong6-45/+283
Add lro/tso and rx checksum support. lro/tso is configured via startup.conf vmxnet3 { lro } It is disable by default due to not all versions of ESXi supports it. Change-Id: Icf224ff528884ecd9e655b4fcf4481194e8c5a63 Signed-off-by: Steven Luong <sluong@cisco.com>

2019-02-02vmxnet3: multiple TX queues supportSteven Luong9-182/+296
Add num-tx-queues to the vmxnet3 create CLI/API. Default is 1. Max is min (8, the number of cores assigned to VPP). Change-Id: I7e0a659a82d01c719665c228dd8a71e3288a2895 Signed-off-by: Steven Luong <sluong@cisco.com>

Allocate physmem on the same numa set link speed cap vmxnet3 support version to 3 if the device supports higher version Change-Id: Id47dd83b0da53e623fd6cf3ad010e58158b1ab15 Signed-off-by: Steven <sluong@cisco.com>
2018-12-17vmxnet3: support clear hardware interface countersSteven3-20/+60
Add clear hardware interface counters callback for vmxnet3 device. We take a snap shot of the statistics in the callback. For the show hardware command, we display the delta between the current statistics and the last snapshot. Change-Id: Ie1389d2141f519300f427fe6ff2fdf97fd9e9378 Signed-off-by: Steven <sluong@cisco.com>
2018-11-13vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)Damjan Marion1-1/+1
Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-11-07vmxnet3: reduce calling vmxnet3_reg_write_inlineSteven3-8/+18
In output.c, we buffer the descriptors and call vmxnet3_reg_write_inline once outside the loop. This change improves the performance dramatically. When refilling the ring, there is no need to inform the device unless explicitly specified by the device (ctrl.update_prod == 1) Change-Id: I7031d58bff0d249e913d14236d416c91eb6ab94a Signed-off-by: Steven <sluong@cisco.com>
2018-10-27vmxnet3: add logging support to the control plane [VPP-1470]Steven4-17/+87
There are different flavors of vmxnet3 device, esxi server, vm fusion, vmware workstation, and vmware player, that we need to communicate with. Each of them also has different versions. We really need the control plane logging to debug when things don't work as expected. Change-Id: I53c23cf10958bfbc06abb1c252d368003563cd04 Signed-off-by: Steven <sluong@cisco.com>

2018-10-16vmxnet3: show vmxnet3 with filtering capability [VPP-1452]Steven3-12/+234
show vmxnet3 desc may display 5000 lines of output since it has 5 tables. Each table may have 1000 entries. It would not be very useful to debug problem. We need filtering capability for the subject show command. We need to be able to display the descriptor table per interface, per interface per table, and per interface per table per slot. The latter is the most useful. tested the following valid combinations show vmxnet3 show vmxnet3 desc show vmxnet3 vmxnet3-0/13/0/0 show vmxnet3 vmxnet3-0/13/0/0 desc show vmxnet3 vmxnet3-0/13/0/0 rx-comp show vmxnet3 vmxnet3-0/13/0/0 rx-comp 1 show vmxnet3 vmxnet3-0/13/0/0 tx-comp show vmxnet3 vmxnet3-0/13/0/0 tx-comp 1 show vmxnet3 vmxnet3-0/13/0/0 rx-desc-0 show vmxnet3 vmxnet3-0/13/0/0 rx-desc-0 1 show vmxnet3 vmxnet3-0/13/0/0 rx-desc-1 show vmxnet3 vmxnet3-0/13/0/0 rx-desc-1 1 show vmxnet3 vmxnet3-0/13/0/0 tx-desc show vmxnet3 vmxnet3-0/13/0/0 tx-desc 1 negative tests and command is rejected show vmxnet3 abc show vmxnet3 desc abc show vmxnet3 vmxnet3-0/13/0/0 abc show vmxnet3 vmxnet3-0/13/0/0 desc abc show vmxnet3 vmxnet3-0/13/0/0 rx-comp abc show vmxnet3 vmxnet3-0/13/0/0 rx-comp 1 abc Change-Id: I0ff233413496e58236f8fb4a94e493494c20c5cb Signed-off-by: Steven <sluong@cisco.com>
2018-10-16vmxnet3: vmxnet3_test_plugin.so: undefined symbol: format_vlib_pci_addr ↵Steven1-1/+9
[VPP-1456] When using vpp_api_test, there is an undefined symbol error for format_vlib_pci_addr when vmxnet3_test_plugin.so is loaded. The cause is due to vlib not included in vpp_api_test. Remove the reference for vlib.so in vmxnet3_test.

2018-10-10vmxnet3: better error handlingSteven2-20/+42
try harder on output - if there is no descriptor space available, try to free up some and check again. make sure we free the buffer if error is encoutered on input. Change-Id: I41a45213e29de71935afe707889e515037cd081f Signed-off-by: Steven <sluong@cisco.com>
2018-10-03vmxnet3: coverity woeSteven2-12/+12
Coverity complains that hb might be null when !prev_b0 is true. It may be right, but not likely. To make the code more explicit when it parses a complete packet, set got_packet = 1 and test got_packet instead of prev_b0 which is somewhat obscure. Use vlib_buffer_free_one rather than vlib_buffer_free_no_next in output.c which takes care of chain buffers.

2018-09-20vmxnet3: invoke vlib_buffer_enqueue_to_next() with the wrong buffers for ↵Steven1-7/+8
chain buffers If we invoke the subject API with 2 buffers, each with 2 chains, the content of buffers[0] should be head of 1st buffer, and content of buffer[1] should be head of 2nd buffer. What the code did was to put buffers[0] = head of 1st buffer buffers[1] = next chain of 1st buffer buffers[2] = head of 2nd buffer buffers[3] = next chain of 2nd buffer This is wrong and can cause crash. The fix is to only increment bi when the entire packet is found which may consist of multiple fragments. Change-Id: If02cd5186a039d7a6c08a0959112840bdb242317 Signed-off-by: Steven <sluong@cisco.com>
