[PATCH 04/10] fnic: Fix SGEs limit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
