Make the needed changes for the new scheme especially around PHY initialization, and link detection. - The get_emac_base function was changed to enable setting different MAC access setting for each PHY based of external configuration. - As a part of the dual-media preparation, the save_spirom_version was modified to accept a PHY specific version address to be saved in the shmem. This will enable to save more than single spirom version in different locations. - The test_link function was changed also as a preparation for the dual-media upcoming changes - Duplicate initialization logic was removed from the link_setting_status and link_initialize functions Signed-off-by: NYaniv Rosner <yanivr@broadcom.com> Signed-off-by: NEilon Greenstein <eilong@broadcom.com> Signed-off-by: NDavid S.

Move the code into PHY oriented functions, and for that a new structure is defines for each PHY which contain PHY properties and its own functions. This also enables to encapsulate all PHY specific operations into the PHY functions. During initialization, the PHYs will be probed by the "bnx2x_phy_probe" function to detect which PHYs exist on-board, and configure them accordingly. Note that the ext_phy_reset implementation was incorporated in the ext_phy_init since it is actually part of the PHY initialization procedure.

The function has an unsigned return type, but returns a negative constant to indicate an error condition. The result of calling the function is always stored in a variable of type (signed) int, and thus unsigned can be dropped from the return type.

This showed up in my audit because we use strcpy() to copy "ds" into a 32 character buffer inside the isdn_tty_dial() function. But it turns out that we only ever use the first 32 characters so it's OK. I have changed the declaration to make the static checkers happy.

This patch enables TCP checksum offload support for IPv6 on ibmveth. This completely eliminates the generation and checking of the checksum for IPv6 packets that are completely virtual and never touch a physical network. A basic TCPIPV6_STREAM netperf run showed a ~30% throughput improvement when an MTU of 64000 was used. This featured is enabled by default, as is the case for IPv4 checksum offload. When checksum offload is enabled the driver will negotiate IPv4 and IPv6 offload with the firmware separately and enable what is available. As long as either IPv4 or IPv6 offload is supported and enabled the device will report that checksum offload is enabled. The device stats, available through ethtool, will display which checksum offload features are supported/enabled by firmware. Performance testing against a stock kernel shows no regression for IPv4 or IPv6 in terms of throughput or processor utilization with checksum disabled or enabled.
