Since not every chip has a Global2 set of registers, make its support optional, in which case the related functions will return -EOPNOTSUPP. This also allows to reduce the size of the mv88e6xxx driver for devices such as home routers embedding Ethernet chips without Global2 support. It is present on most recent chips, thus enable its support by default. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This registers set at internal SMI address 0x1C provides extended
|
|
features like EEPROM interface, trunking, cross-chip setup, etc.
|

It is required on most chips. If the chip you compile the support for
|
|
doesn't have such registers set, say N here. In doubt, say Y.
