Hi everybody. First of all, I'd like to say please for give me. ;-) Test results I've posted already are not correct result. It's my fault. anyway, I fixed them. consequently, I found out that every entry value of indirection table is mapping just one RX queue index. But, still there is a problem that is every RX queue index number is different with entry value of indirection table. I'm investigating the reason.
Thanks. 배영부 쓴 글: > Hi there. > > I'm evaluating RSS(Receive-Side Scaling) feature of Intel 82598EB NIC. > I'm evaluating it with two of Quad core Xeon CPUs - as a result, there > are 4 cpu cores - and ixgbe device driver > version 1.3.56.
