2020-11-10classify: fix classify filter trace del cli processingJon Loeliger1-35/+49
When a 'del' is used to delete a classify table, only the mask is needed to locate the table. Any match vector is unneeded. The tests failed to notice this, but if the test is run by hand in vppctl, it issues a parse error. Fix the test so that it doesn't supply irrelevant data. Fix the CLI processing to read always complete newline terminated line of input instead. This allows unneeded CLI parameters to be ignored. It also necessitated fixing a trace test which had then erroneously split a single CLI command over multiple lines. While in the area, fix a latent bug on table matching where a test for compatible mask vector sizes were not matching impedance properly (byte vs ux32x4).

2020-11-05tap: allow change of carrier state on hostMatthew Smith4-0/+45
Type: feature Add a function to adjust the link state of the host side of a tap interface. If an application (e.g. route protocol daemons) running on the host uses netlink to monitor interface state, a plugin could use this function to communicate a loss of connectivity to the application by making the interface appear to go down. Requires a somewhat recent kernel. E.g. it does not have any effect on CentOS 7 but it works on CentOS 8.

2020-10-21virtio: run process to send interrupts to input nodesMohsin Kazmi4-17/+112
Type: improvement virtio interfaces support packet coalescing and buffering which depends on timer expiry to flush the stored packets periodically. virtio input node checks timer expiry and schedules tx queue accordingly. In poll mode, timer expiry is handled naturally, as input node runs periodically. In interrupt mode, virtio input node depends on the interrupts send from backend. Stored packets could starve, if there would not be interrupts to input node. This patch implements a process node which periodically sends interrupt to virtio input node given coalescing or buffering feature is enabled on an interface.
