I must be dealing with the wrong documents. I am using the latest 82599 and x540 data sheets, and their specification updates. I tried logging onto my Intel support account, but cannot find any ixgbe related documents with a section 4.4.3.5.12. Am I missing something basic? Fred On 2012-11-03 7:5

Hi, I am trying to understand the meaning of IXGBE_DROPEN, defined in ixgbe-3.11.33 ixgbe_type.h and reported in ixgbe_ethtool.c. I cannot find any reference in the data sheet. Is this an undocumented register? Thanks, Fred. ---

Nagel algorithm. These delays are quite significant for our application and it would be great to get rid of them. I tried all module parameters and I tried modifying some defaults such as BURST_RDTR. Is there anything we can do to eliminate these delays? -- Fred Klassen F
