crypto: CLI to change dispatch mode
This change aims to affect crypto_sw_scheduler behavior, but all the edits end up in vnet/crypto. After 9a9604b introduced adaptive mode for crypto dispatch, the performance of async mode at lower rate got worse. A work around for CSIT test is done by changing dispatch mode via explicit API call in https://github.com/FDio/vpp/commit/139aba204780f6cc2845b311820a0b4c47517d02 In this change, the CLI is brought back to allow user to fix the dispatch mode. set crypto async dispatch mode <polling|interrupt|adaptive> Type: improvement Change-Id: I029e98aa25889eddcf62e75a6c78926cdee862ef Signed-off-by: Niyaz Murshed <niyaz.murshed@arm.com>
