Hi,
my output of command :
ethtool -g em1
Ring parameters for em1:
Pre-set maximums:
RX: 4096
RX Mini: 0
RX Jumbo: 0
TX: 4096
Current hardware settings:
RX: 1024
RX Mini: 0
RX Jumbo: 0
TX: 1024
before current value for RX and TX are 256 and i increased it by 1024
for both RX and TX. But still we having packet loss on interface.
How to verify that buffer full for RX and TX?
Regards,
Benjo
