ixgbe: DCB, return max for IEEE traffic classes 2011-11-02T23:55:55+00:00 John Fastabend john.r.fastabend@intel.com 2011-10-19T08:48:49+00:00 8599e251b3dd18c7bcb342d5b4acecc420f43606 Returning the max traffic classes on get requests simplifies user space configurations because applications will know explicitly how many traffic classes can be used. Typical switch implementations use 2 or 3 traffic classes so this not seen often today. And user space can learn the number of traffic classes by return codes but this allows user space to configure ixgbe correctly at the start.

This patch fixes some issues found in the buffer read portion of
ixgbe_host_interface_command()

- use `bi` as the buffer index counter instead of `i`
- add conversion to native cpu byte ordering on register read
- fix conversion from bytes to dword
- use dword_len instead of buf_len when reading the register
