We connected two smart bits ports to two Ethernet ports on the Linux
system, Smartbits pumps traffic on one port and receives traffic on
other port, we are getting higher through with lower packet size, and
getting lower throughput with higher packet size. If the packet size is
smaller, I should get more packets and which interrupts more and I
should get lower throughput, Does this some issue with Bottom halfs in
my Network driver?. Any idea?. Thanks.
