3.5.2.10.1.5 Hash for IPv6 with UDP
Similar to above:
Input[36] = @8-23, @24-39, @40-41, @42-43
Result = ComputeHash(Input, 36)
3.5.2.10.1.6 Hash for IPv6 without TCP
Input[32] = @8-23, @24-39
Result = ComputeHash(Input, 32)
3.5.2.10.2 Indirection Table
The indirection table is a 128-entry structure, indexed by the seven LSBs of the hash function output.
Each entry of the table contains the following:
• Bits [3:0] – RSS output index 0
• Bits [7:4] – RSS output index 1 (optional)
System software can update the indirection table during run time. Such updates of the table are not
synchronized with the arrival time of received packets. Therefore, it is not guaranteed that a table
update takes effect on a specific packet boundary.
3.5.2.10.3 RSS Verification Suite
Assume that the random key byte-stream is:
0x6d, 0x5a, 0x56, 0xda, 0x25, 0x5b, 0x0e, 0xc2,
0x41, 0x67, 0x25, 0x3d, 0x43, 0xa3, 0x8f, 0xb0,
0xd0, 0xca, 0x2b, 0xcb, 0xae, 0x7b, 0x30, 0xb4,
0x77, 0xcb, 0x2d, 0xa3, 0x80, 0x30, 0xf2, 0x0c,
0x6a, 0x42, 0xb7, 0x3b, 0xbe, 0xac, 0x01, 0xfa
