lpfc_nvme_enable_fb Enables NVMe first burst on initiator and target
functions.
For an initiator, enabling this parameter means that an
NVMET PRLI response with FBA enabled and an
FB_SIZE set to a nonzero value is processed by the
initiator for subsequent NVMe FCP I/O.
Currently, this feature is not supported on NVMe
targets.
The possible values are:
0 = Disabled (default)
1 = Enabled

lpfc_nvme_oas When enabled, uses the oas bit when sending NVMe/
NVMe target I/Os.
The possible values are:
0 = Disabled (default)
1 = Enabled

Dynamic
lpfc_nvmet_fb_size When enabled, communicates the first burst size of
the target to the NVMe initiator in the PRLI response.
lpfc_nvmet_fb_size is used only when the
lpfc_nvme_enable_fb is set and the target sends
a PRLI response.
The possible values are:
0 = Disabled (default)
1 = Enabled
This parameter is supported only on physical ports.

lpfc_ras_fwlog_buffsize Specifies the buffer size to be allocated in host
memory for firmware logging.
The possible values are:
 0 = Disables the firmware log written to the host
memory (default).
 1 = ¼ MB (256K) host memory to be allocated for
the firmware log.
 2 = ½ MB (512K) host memory to be allocated for
the firmware log.
 3 = ¾ MB (768K) host memory to be allocated for
the firmware log.
 4 = 1 MB host memory to be allocated for the
firmware log.

lpfc_ras_fwlog_level Configures the firmware logging level. Valid only if
