What I need to know:
- how to load UEFI Driver from NIC's flash? (for demo purposes it could be 'how to load whatever from whenever', just to show that such operation is possible)
- where to load that driver? (RAM/HDD)
- when translate UEFI Driver to linux-understandable format (on boot, or on each call)
From the OS you cannot load the UEFI driver from the NIC flash because, according to you, there is no UEFI driver in place to access the NIC flash in the first place. Your NIC is unknown to UEFI if it cannot be enumerated. Chicken and egg situation. Now if you set up things so that your NIC is found when UEFI is probing devices, then you could write an UEFI app that could access the NIC flash, get driver image and store it in the ESP. It could then unload the existing driver and load the new driver in its place. All this needs to be done before the OS boots.

You cannot translate UEFI driver to "linux-understandable format." Period. UEFI using protocols and Linux uses APIs. They use different calling conventions also. A UEFI driver has no place in the Linux kernel.

MY(4)							   BSD Kernel Interfaces Manual 						     MY(4)

NAME

     my -- Myson Technology Ethernet PCI driver

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device my

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_my_load="YES"

DESCRIPTION

     The my driver provides support for various NICs based on the Myson chipset.  The Myson chipset is a variant of the DEC Tulip NIC chipset.

     The driver will work with almost any MII-compliant PHY, thus failure to positively identify the chip is not a fatal error.

HARDWARE

     The my driver provides support for various NICs based on the Myson chipset.  Supported models include:

     o	 Myson MTD800 PCI Fast Ethernet chip
     o	 Myson MTD803 PCI Fast Ethernet chip
     o	 Myson MTD89X PCI Gigabit Ethernet chip

SEE ALSO

     altq(4), de(4), netintro(4), pci(4), ifconfig(8)

HISTORY

     The my driver first appeared in FreeBSD 4.6.

AUTHORS

     The my driver was written by Myson Technology Inc.

     This manual page was written by Hiten M. Pandya <hmp@FreeBSD.org>.

BUGS

     The my driver does not support Power Management Events (PME).
