Configure 'IO_TLB_SEGSIZE' at runtime?

[aakarshcool15-crypto]

Hi,

Is there any way that we can configure 'IO_TLB_SEGSIZE' at runtime with some kernel boot args?
128 * 2 = 256KB per slot seems to be very small in accomodating very large buffers.
I understand there is kernel command line parameter for increasing bounce buffer pool size. Similar to this, do we have kernel cmd line parameter for 'IO_TLB_SEGSIZE' so that we can escape recompiling kernel again and again.

Thanks in advance!!
