Update Chelsio gige net driver.
- Use extern prefix for functions required.
- Removed a lot of wrappers, including t1_read/write_reg_4.
- Removed various macros, using native kernel calls now.
- Enumerated various #defines.
- Removed a lot of shared code which is not currently used in "NIC only" mode.
- Removed dead code.
Documentation/networking/cxgb.txt:
- Updated release notes for version 2.1.1
drivers/net/chelsio/ch_ethtool.h
- removed file, no longer using ETHTOOL namespace.
drivers/net/chelsio/common.h
- moved code from osdep.h to common.h
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/cphy.h
- removed dead code.
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/cxgb2.c
- use DMA_{32,64}BIT_MASK in include/linux/dma-mapping.h.
- removed unused code.
- use printk message for link info resembling drivers/net/mii.c.
- no longer using the MODULE_xxx namespace.
- no longer using "pci_" namespace.
- no longer using ETHTOOL namespace.
drivers/net/chelsio/cxgb2.h
- removed file, merged into common.h
drivers/net/chelsio/elmer0.h
- removed dead code.
- added various enums.
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/espi.c
- removed various macros, using native kernel calls now.
- removed a lot of wrappers, including t1_read/write_reg_4.
drivers/net/chelsio/espi.h
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/gmac.h
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/mv88x201x.c
- changes to sync with Chelsio TOT.
drivers/net/chelsio/osdep.h
- removed file, consolidation. osdep was used to translate wrapper functions
since our code supports multiple OSs. removed wrappers.
drivers/net/chelsio/pm3393.c
- removed various macros, using native kernel calls now.
- removed a lot of wrappers, including t1_read/write_reg_4.
- removed unused code.
drivers/net/chelsio/regs.h
- added a few register entries for future and current feature support.
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/sge.c
- rewrote large portion of scatter-gather engine to stabilize
performance.
- using u8/u16/u32 kernel types instead of __u8/__u16/__u32 compiler
types.
drivers/net/chelsio/sge.h
- rewrote large portion of scatter-gather engine to stabilize
performance.
- added comment to #endif indicating which symbol it closes.
drivers/net/chelsio/subr.c
- merged tp.c into subr.c
- removed various macros, using native kernel calls now.
- removed a lot of wrappers, including t1_read/write_reg_4.
- removed unused code.
drivers/net/chelsio/suni1x10gexp_regs.h
- modified copyright and authorship of file.

drivers/net/chelsio/tp.c
- removed file, merged into subr.c.
drivers/net/chelsio/tp.h
- removed file.
include/linux/pci_ids.h
- patched to include PCI_VENDOR_ID_CHELSIO 0x1425, removed define from
our code.
