octeontx2-af: cn10k: Set NIX DWRR MTU for CN10KB silicon
The DWRR MTU config added for SDP and RPM/LBK links on CN10K
silicon is further extended on CK10KB silicon variant and made
it configurable. Now there are 4 DWRR MTU config to choose while
setting transmit scheduler's RR_WEIGHT.
Here we are reserving one config for each of RPM, SDP and LBK.
NIXX_AF_DWRR_MTUX(0) ---> RPM
NIXX_AF_DWRR_MTUX(1) ---> SDP
NIXX_AF_DWRR_MTUX(2) ---> LBK
PF/VF drivers can choose the DWRR_MTU to be used by setting
SMQX_CFG[pkt_link_type] to one of above. TLx_SCHEDULE[RR_WEIGHT]
is to be as configured 'quantum / 2^DWRR_MTUX[MTU]'. DWRR_MTU
of each link is exposed to PF/VF drivers via mailbox for
RR_WEIGHT calculation.
