H A D | caamrng.c | 61bb86bb Fri Jul 13 17:49:28 CDT 2012 Kim Phillips <kim.phillips@freescale.com> crypto: caam - set descriptor sharing type to SERIAL
SHARE_WAIT, whilst more optimal for association-less crypto, has the ability to start thrashing the CCB descriptor/key caches, given high levels of traffic across multiple security associations (and thus keys).
Switch to using the SERIAL sharing type, which prefers the last used CCB for the SA. On a 2-DECO platform such as the P3041, this can improve performance by about 3.7%.
