Introduce buffered read/writes which greatly improves performance on parts with large EEPROMs. Previously reading/writing a word requires taking/releasing of synchronization semaphores which adds 10ms to each operation. The optimization is to read/write in buffers, but make sure the semaphore is not held for >500ms according to the datasheet. Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is used to discover the EEPROM size when needed and keeps the result in word_page_size for the rest of the run time. Use buffered reads for ethtool -e. Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Evan Swanson <evan.swanson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
