Could anyone tell me why this routine in mthca is necessary? There
aren't any comments to explain it; I'm wondering if this is a workaround
for Sinai of some kind?
static inline u32 adjust_key(struct mthca_dev *dev, u32 key)
{
if (dev->mthca_flags & MTHCA_FLAG_SINAI_OPT)
return ((key << 20) & 0x800000) | (key & 0x7fffff);
else
return key;
}
Thanks in advance,
Jesse
