Subject: [PATCH] Consolidate shared code between enic and fnic drivers.
Consolidate shared code between enic and fnic drivers.
[David/James, we need a little help with this one...this single patch
spans scsi and netdev, so we're not sure which tree/maintainer needs
to pick up the patch. Please advise. It's for 2.6.31. The patch is
against linux-2.6.git.]
The Cisco enic 10G Ethernet driver and the fnic FCoE HBA driver share
much of the same hardware-access code because enic and fnic devices are
really two functions on a converged-I/O PCIe device. This patch
consolidates the shared code into one shared module, thus eliminating
the code duplication. No functional changes are made by the patch.
Why weren't these consolidated in the first place? fnic went in late in
2.6.30 on the scsi branch (merge exception for new drivers), and it was
too late to modify enic which was already included in 2.6.28.
The changes are as follows:
o a new module vnic which is shared between fnic and enic
o vnic files reside in drivers/net/enic
o fnic Makefile includes vnic files from drivers/net/enic
