of API helps to list all supported tables.\nIn the near future, only the CT table is planned\nto be used, so only one identifier for this table\nwas added to the efx.\nNew table IDs will be added as needed.\n\nSigned-off-by: Denis Pryazhennikov <denis.pryazhennikov@arknetworks.am>\nReviewed-by: Andy Moreton <amoreton@xilinx.com>\n---\n drivers/common/sfc_efx/base/efx.h | 15 ++++\n
