1842 * Macro that given an attr e.g. hba_queue_depth expands
1843 * into a function with the name lpfc_hba_queue_depth_init. The macro also
1844 * takes a default argument, a minimum and maximum argument.
1845 *
1846 * lpfc_##attr##_init: validates the min and max values then sets the
1847 * adapter config field accordingly, or uses the default if out of range
1848 * and prints an error message.
1849 * @phba: pointer the the adapter structure.
1850 * @val: integer attribute value.
1851 *
1852 * Returns:
1853 * zero on success
1854 * -EINVAL if default used

3826 * If the val is 0 and currently the device's AER support was enabled,
3827 * invoke the kernel's disable AER helper routine. After that, update
3828 * the device's cfg_aer_support flag to indicate AER is not supported
3829 * by the device; otherwise, if the device AER capability is already

4581# parses REPORT_LUN responses. The lpfc driver has no LUN count or
4582# LUN ID limit, but the SCSI midlayer requires this field for the uses
4583# above. The lpfc driver limits the default value to 255 for two reasons.
4584# As it bounds the sequential scan loop, scanning for thousands of luns
4585# on a target can take minutes of wall clock time. Additionally,
4586# there are FC targets, such as JBODs, that only recognize 8-bits of
4587# LUN ID. When they receive a value greater than 8 bits, they chop off
4588# the high order bits. In other words, they see LUN IDs 0, 256, 512,
4589# and so on all as LUN ID 0. This causes the linux kernel, which sees
4590# valid responses at each of the LUN IDs, to believe there are multiple
4591# devices present, when in fact, there is only 1.
