probe_vf: Either a single value (e.g. '3') to indicate that the Hypervi-

sor driver itself should activate this number of VFs for each

HCA on the host, or a string to map device function numbers to

their probe_vf values (e.g. '0000:04:00.0-3,002b:1c:0b.a-13').

Hexadecimal digits for the device function (e.g. 002b:1c:0b.a)

and decimal for probe_vf value (e.g. 13). (string)

log_num_mgm_entry_size: log mgm size, that defines the num of qp per mcg, for example:

10 gives 248.range: 7 <= log_num_mgm_entry_size <= 12. To

activate device managed flow steering when available, set to -

1 (int)

high_rate_steer: Enable steering mode for higher packet rate (default off)

(int)

fast_drop: Enable fast packet drop when no recieve WQEs are posted (int)

enable_64b_cqe_eqe: Enable 64 byte CQEs/EQEs when the FW supports this if non-zero

(default: 1) (int)

log_num_mac: Log2 max number of MACs per ETH port (1-7) (int)

log_num_vlan: (Obsolete) Log2 max number of VLANs per ETH port (0-7) (int)

log_mtts_per_seg: Log2 number of MTT entries per segment (0-7) (default: 0) (int)

port_type_array: Either pair of values (e.g. '1,2') to define uniform port1/

port2 types configuration for all devices functions or a

string to map device function numbers to their pair of port

types values (e.g. '0000:04:00.0-1;2,002b:1c:0b.a-1;1').

Valid port types: 1-ib, 2-eth, 3-auto, 4-N/A

If only a single port is available, use the N/A port type for

port2 (e.g '1,4').

log_num_qp: log maximum number of QPs per HCA (default: 19) (int)

log_num_srq: log maximum number of SRQs per HCA (default: 16) (int)

log_rdmarc_per_qp: log number of RDMARC buffers per QP (default: 4) (int)

log_num_cq: log maximum number of CQs per HCA (default: 16) (int)

log_num_mcg: log maximum number of multicast groups per HCA (default: 13)

(int)

log_num_mpt: log maximum number of memory protection table entries per HCA

(default: 19) (int)

log_num_mtt: log maximum number of memory translation table segments per

HCA (default: max(20, 2*MTTs for register all of the host mem-

ory limited to 30)) (int)

enable_qos: Enable Quality of Service support in the HCA (default: off)

(bool)

internal_err_reset: Reset device on internal errors if non-zero (default is 1)

(int)
