Subject: [PATCH 06/12] sfc: Remove EFX_WORKAROUND_9141 macro

From: Ben Hutchings <[email-masked]>
Date: Sat, 28 Nov 2009 15:35:24 +0000

From: Matthew Slattery <[email-masked]>

The "bug9141 workaround" of setting TX_FLUSH_MIN_LEN_EN should really
be considered as a normal bit of configuration rather than a
workaround.
