bnx2x: New link code
New Link code: Moving all the link related code (including the calculations, the initialization of the MAC and PHY and the external PHY's code) into a separated file. The changes from the code that used to be part of bnx2x.c (now called bnx2x_main.c) are: - Using separate structures for link inputs and link outputs to clearly identify what was configured and what is the outcome - Adding code to read external PHY FW version and print it as part of ethtool -i - Adding code to upgrade external PHY FW from ethtool -E with special magic number - Changing the link down indication to ERR level - Adding a lock on all PHY access to prevent an interrupt and setting changes to overlap - Adding support for emulation and FPGA (small chunk of code that really helps in the lab) - Adding support for 1G on BCM8706 PHY - Adding clear debug print incase of fan failure (the PHY type is now "failure") Signed-off-by: Yaniv Rosner <yanivr@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
