10.2.1.3.26 Redirection Table - RETA (0x05C00 + 4*n (n=0…31); RW)
Note:
10.2.1.3.27 Random Key Register - RSSRK (0x05C80 + 4*n (n=0…9); RW)
155
The re-direction table is a 32 entry table. Each entry is composed of four tags each 8-
bits wide. Only the first or last six bits of each tag are used (five bits for the CPU index
and 1 bit for queue index).
RETA cannot be read when RSS is enabled.
The RSS Random Key register stores a 40-byte key (10 Dword entry table) used by the
RSS hash function.
