Driver allows IOs with more SGEs than max SGEs supported by Palo. The current
max SGEs
supported by the fnic driver is 1024. The current register settings on Palo
supports
a max of 256 only. Palo would return any IO with more than 256 SGEs with an
error
indicating INVALID_SGLS. Fnic driver should limit the max supported SGLs in
the driver to 256 to avoid this error.
