Subject: rx_copybreak value for non-i386 architectures
Date: Tue, 27 Feb 2001 18:32:22 -0800	[thread overview]
Message-ID: <3A9C6336.D2E086A6@mvista.com> (raw)


I notice that many net drivers set rx_copybreak to 1518 (the max packet size)
for non-i386 architectures.  Once I thought I understood it and it seems
related to cache line alignment.  However, I am not sure exactly about the
reason now.  Can someone enlighten me a little bit?

Basically I try to understand whether for MIPS architectures we need to set
this value as well.

Please CC your reply to my email address.

TIA.
