2021-02-05devices: af-packet gso mtuNathan Skrzypczak1-0/+1
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.

2018-02-06vlib: epoll on worker threadsDamjan Marion1-0/+2
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>
2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-1/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-10-11Revert "VPP-1001 - update AF Packet Driver to for modern kernels"Damjan Marion1-3/+0
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 Ivanov1-0/+3
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 Kinsella1-0/+1
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.
