Type: improvement Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com> Change-Id: I3ec857adb3a9e8a778072a202a4d23f4101e83b2
2022-10-25devices: fix the l2 hdr offset in af_packet transmit sideMohsin Kazmi1-4/+2
Type: fix af_packet transmit node uses header offsets to set the appropriate metadata for packet with offload. But l2_hdr_offset is not correctly set by previous node. This patch makes use of curren_data field as l2_hdr_offset. Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com> Change-Id: I751a725af5c231a443eed22231a867eb7f3894e0

2021-09-07devices: restore regular af-packet tx pathMohammed Hawari1-21/+19
This change restores the af_packet tx path prior in use prior to Change Idf0bdd88990254a614962c2f7bc3e0292ccfd61a but fixes the stalling issue by ensuring that the next tx frame pointer is only incremented when a new tx frame is used. This change also enables the af_packet PACKET_QDISC_BYPASS option, for better performance.

Type: fix Set the GSO flag when buffer length exceeds the linux mtu. Don't listen for mtu changes on linux side for now. This also fixes a TX issue, as we only search for valid frames on tx to the extent of n_left, we might stay stuck.

2018-02-07af_packet: Fix lock positionPierre Pfister1-2/+1
In multi-worker cases, af-packet tx was subject to a pretty serious race condition as the device lock was obtained after some queue values were read from queue. Result could go from packet loss to queue inconsistency, leading to tx being stuck for 'some time'. The fix is really simple. Finding the problem was not...

2018-02-06vlib: epoll on worker threadsDamjan Marion1-1/+1
This patch teaches worer threads to sleep and to be waken up by kernel if there is activity on file desctiptors assigned to that thread. It also adds counters to epoll file descriptors and new debug cli 'show unix file'. Change-Id: Iaf67869f4aa88ff5b0a08982e1c08474013107c4 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-10-11Revert "VPP-1001 - update AF Packet Driver to for modern kernels"Damjan Marion1-29/+1
Issues observed with specific kernel versions, e.g. stock Ubuntu 16.04 kernel. This reverts commit 3eab064e3fadaf2a6a128f167ad04ca0319b4e17. Change-Id: I24241f3b580df749fc686af3a319011ca035fb5e Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-10-04VPP-1001 - update AF Packet Driver to for modern kernelsAnton Ivanov1-1/+29
1. Add VNET headers support for checksumming - required to operate correctly on any recent Linux 2. Bypass QDISC on transmit - improves performance by ~ 5%. Enabled only if the macro is detected - apparently not present on archaic distributions. This still does not solve all issues with TSO - it can be fixed only by going to tpacket v3 and dynamic rx ring as well as significant changes in the TX (sendmmsg?).

2017-04-28af_packet: reflect admin device state on hostRay Kinsella1-3/+39
Setting the interface state in VPP on an af_packet device, was not being reflected on the host. This implied the user had to set the device state in VPP and then on the host, in order to put the interface into an 'up' state. This changes makes the device state consisent in VPP and the host.

2017-03-28af_packet driver needs to check VLIB_BUFFER_NEXT_PRESENT flag is setJim Gibson1-1/+2
when walking vlib_buffer_t next_buffer chain on transmit. On buffer allocation: - next_buffer is not and may contain a stale invalid value that should be ignored if not overwritten by a valid value. - VLIB_BUFFER_NEXT_PRESENT flag is cleared and only set if a valid value is written to next_buffer.
