related to "shared" CPLs. a) Combine t4_set_tcb_field and t4_set_tcb_field_rpl into a single function. Allow callers to direct the response to any iq. Tidy up set_ulp_mode_iscsi while there to use names from t4_tcb.h instead of magic constants. b) Remove all CPL handler tables from struct adapter. This reduces its size by around 2KB. All handlers are now registered at MOD_LOAD instead of attach or some kind of initialization/activation. The registration functions do not need an adapter parameter any more. c) Add per-iq handlers to deal with CPLs whose destination cannot be determined solely from the opcode. There are 2 such CPLs in use right now: SET_TCB_RPL and L2T_WRITE_RPL. The base driver continues to send filter and L2T_WRITEs over the mgmtq and solicits the reply on fwq. t4_tom (including the DDP code) now uses the port's ctrlq to send L2T_WRITEs and SET_TCB_FIELDs and solicits the reply on an ofld_rxq. fwq and ofld_rxq have different handlers that know what kind of tid to expect in the reply. Update t4_write_l2e and callers to to support any wrq/iq combination. Approved by: re@ (kib@) Sponsored by: Chelsio Communications
