rte_eal_init() arg '-c' is deprecated in DPDK 25.07.
So we will need to replace converting dpdk-lcore-mask to -c at least for
use of DPDK 25.11. In fact, we don't need to wait for DPDK 25.11,
because we can do this now by using '--lcores' instead of '-c'.
This also adds compatability for using a core greater than the max
lcore value, similar to commit:
fe53b478f86e ("dpdk: Fix main lcore on systems with many cores.")
Masks with invalid core numbers and total number of cores are also handled
more gracefully, as they are not blindly passed to DPDK.
The first 2 patches are minor cleanups:
- vswitch.xml is updated as the old dpdk-lcore-mask description was
a bit misleading.
- Some of the added default handling was not used, so we can remove it.
v3:
Reworked for Eelco and Ilya's comments.
- 1/3: updated vswitch.xml description
- 3/3: used ds_put_format. Updated log. Moved test macro.
v2:
Reworked for David's comments.
- 2/3: added this cleanup
- 3/3: reworked to simplify and reuse existing mask parsing. Changed test cases.
Kevin Traynor (3):
vswitch.xml: Update docs for dpdk-lcore-mask.
dpdk: Clean up dpdk option map.
dpdk: Convert dpdk-lcore-mask to DPDK lcore args.
