ethtool.8: Improve description of --flash option
Avoid repeating 'flash' as a verb; that doesn't explain anything. For consistency, describe both parameters (aside from devname) under separate headings, formatted as lower-case italic. Explain how the filename is resolved. Explain what non-zero values of N would mean, and that they are driver-dependent. Signed-off-by: Ben Hutchings <>
