2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-9/+12
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-11-09vlib: fix trace number accountingBenoît Ganne1-11/+12
When using classifier to filter traces, not all packets will be traced. In that case, we should only count traced packets. Type: fix Change-Id: I87d1e217b580ebff8c6ade7860eb43950420ae78 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2019-09-02vmxnet3: interface rx counter not increment correctlySteven Luong1-1/+1
vlib_increment_combined_counter takes sw_if_index, not hw_if_index. Using hw_if_index may work as long as there is no subinterface created to cause hw_if_index and sw_if_index to differ. Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: If50412dc1e84c4f1f5b977b58d0e1aeb5ab8ebe6
2019-08-30vmxnet3: per interface gso supportSteven Luong1-1/+1
gso option for vmxnet3 is per VPP process currently. There is no reason why we cannot provide per interface gso support. Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Ife962b52221191050dedd18252b859880ccd7599

2019-05-21vmxnet3: gso_l4_hdr_sz is not set correctlySteven Luong1-16/+24
vnet_buffer2 -> gso_l4_hdr_sz is not set correctly because vnet_buffer->l4_hdr_offset is not set yet at the top. Move the code to set vnet_buffer->gso_l4_hdr_sz further down. Change-Id: I0110e4687572bb93cb593d7d4d14a3d5083af13a Signed-off-by: Steven Luong <sluong@cisco.com>

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>
2018-11-07vmxnet3: reduce calling vmxnet3_reg_write_inlineSteven1-2/+3
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>
2018-10-10vmxnet3: better error handlingSteven1-11/+26
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 woeSteven1-3/+6
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.

outbound -- if we have to drop the packet due to no descriptor space is available, drop the whole packet, not fragments. inbound -- check and drop error packets Change-Id: Ida1d32e61521bafd67f714d729ad53cd7c487dc6 Signed-off-by: Steven <sluong@cisco.com>
2018-09-25vmxnet3: guard against array overflowSteven1-2/+3
Under extreme condition, it is possible for input node to have more than 256 packets available to process. Add a check to the while loop to prevent overrun buffer_indices and nexts. Change-Id: Id9830e5c254f04216eb79e864a5460e08cf2e4e5 Signed-off-by: Steven <sluong@cisco.com>
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>
