This patch adds support for 1G Fiber PHY modules (SFP+ modules). This support
comes along side support for 1G Copper PHY modules, but uses a different PHY
type (ixgbe_sfp_type_1g_sx_core).

This patch adds support for I2C clock stretching which is required per
SFF-8636. Customers with passive DA cables implement clock stretching
would fail without this patch.

The X520 family of network devices, with the 82599 chip, support a
small number of Intel-verified SFP+ modules on their NICs. To maintain
stability and quality, the current devices restrict untested 3rd party
SFP+ modules.
This patch introduces a module parameter for ixgbe to allow these untested
modules at the user's peril. It also includes a warning to the syslog
alerting users that the modules aren't supported, and results may
vary.

I2C access is timing critical. Always do a write flush after writing
to the I2CCTL register.

Please, this kind of stuff rots forever and not using bool properly

I merely installed coccinelle, read the documentation and took credit.

Since ixgbe_raise_i2c_clk() can never return anything else than 0
this patch removes it's return value and all checks for it.

Clear the data field in ixgbe_read_i2c_byte_generic so it does not
accumulate 1 bit using the same variable multiple times.
