[realtek] Flow control question

[Kelvin Proctor]

Dear Realtek List Members,

I'll apologise in advance for what might be a newbie question.

I'm wanting to set a realtek 8139 card to ignore flow control packets (for a
real time system).

I've downloaded and compiled rtl8139-diag.  This has shown that Tx flow
control is enabled.

I assume that I need to rebuild rtl8139-diag and link it against libflash.c
to enable writing to the Flash ROM to do this.  If this is correct I would
like to know how I need to modify the ROM file.

Thank-you for your patience and assistance.

Kelvin Proctor
