Is there any option to increase that 2048 to 2148??
Sometimes when a particular host does not present BIOS entry options for HBA's I've known people put the cards in another machine, set and save the BIOS parameters, and then reinstall the HBA into the required machine.
I may well be wrong but at the moment my money is on the HBA's being unable to communicate because of their configuration settings, and nothing to do with the O/S's, drivers, or anything like that. I say this because you get a "LINK ERROR" which I interpret as a low level communication screw up between the cards. I think that simple interactions work okay (perhaps sending smaller packets to each other) but not bigger operations (perhaps maxing out the packet size) also leads me to think the cards are the issue.
Yes, O/S provided buffer sizes being exceeded could also cause an issue but I wouldn't expect to see "LINK ERROR" in this case.
Also, please confirm that you don't see anything about jumbo packet support in the CTRL-Q setup?

scsi_hba_fini
scsi_hba_init(9F) Kernel Functions for Drivers scsi_hba_init(9F)
NAME
scsi_hba_init, scsi_hba_fini - SCSI Host Bus Adapter system initialization and completion routines
SYNOPSIS
#include <sys/scsi/scsi.h>
int scsi_hba_init(struct modlinkage *modlp);
void scsi_hba_fini(struct modlinkage *modlp);
INTERFACE LEVEL
Solaris architecture specific (Solaris DDI).
PARAMETERS
modlp Pointer to the Host Bus Adapters module linkage structure.
DESCRIPTION
scsi_hba_init()
scsi_hba_init() is the system-provided initialization routine for SCSI HBA drivers. The scsi_hba_init() function registers the HBA in the
system and allows the driver to accept configuration requests on behalf of SCSI target drivers. The scsi_hba_init() routine must be called
in the HBA's _init(9E) routine before mod_install(9F) is called. If mod_install(9F) fails, the HBA's _init(9E) should call scsi_hba_fini()
before returning failure.
scsi_hba_fini()
scsi_hba_fini() is the system provided completion routine for SCSI HBA drivers. scsi_hba_fini() removes all of the system references for
the HBA that were created in scsi_hba_init(). The scsi_hba_fini() routine should be called in the HBA's _fini(9E) routine if mod_remove(9F)
is successful.
RETURN VALUES
scsi_hba_init() returns 0 if successful, and a non-zero value otherwise. If scsi_hba_init() fails, the HBA's _init() entry point should
return the value returned by scsi_hba_init().
CONTEXT
scsi_hba_init() and scsi_hba_fini() should be called from _init(9E) or _fini(9E), respectively.
SEE ALSO
_fini(9E), _init(9E), mod_install(9F), mod_remove(9F), scsi_pktalloc(9F), scsi_pktfree(9F), scsi_hba_tran(9S)
Writing Device Drivers
NOTES
The HBA is responsible for ensuring that no DDI request routines are called on behalf of its SCSI target drivers once scsi_hba_fini() is
called.
