net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5} 2015-04-13T12:02:13+00:00 Markos Chandras markos.chandras@imgtec.com 2015-03-19T10:28:14+00:00 709131497030690fe145a087b1d325a4ae168feb commit 87f966d97b89774162df04d2106c6350c8fe4cb3 upstream. On a MIPS Malta board, tons of fifo underflow errors have been observed when using u-boot as bootloader instead of YAMON. The reason for that is that YAMON used to set the pcnet device to SRAM mode but u-boot does not. As a result, the default Tx threshold (64 bytes) is now too small to keep the fifo relatively used and it can result to Tx fifo underflow errors. As a result of which, it's best to setup the SRAM on supported controllers so we can always use the NOUFLO bit.
