[PATCH] staging: Remove slicoss driver

From: Guenter Roeck

Next message: Herbert Xu: "Re: [PATCH v6 2/2] crypto: add virtio-crypto driver"
Previous message: Jian Yuan: "Re: [PATCH v6] pwm: add pwm driver for HiSilicon BVT SOCs"
Next in thread: Greg Kroah-Hartman: "Re: [PATCH] staging: Remove slicoss driver"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

There is now a different driver for the slicoss devices in
drivers/net/ethernet/alacritech/. That driver supports the same PCI
device IDs as the driver in staging. Both drivers use the same
configuration symbol (CONFIG_SLICOSS), which causes build failures
for the staging driver. Presumably the driver in staging is obsolete
and can be removed.

- This driver supports Alacritech's IS-NIC gigabit ethernet cards.
-
- This includes the following devices:
- Mojave cards (single port PCI Gigabit) both copper and fiber
- Oasis cards (single and dual port PCI-x Gigabit) copper and fiber
- Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber
-
- To compile this driver as a module, choose M here: the module
- will be called slicoss.

-TODO:
- - move firmware loading to request_firmware()
- - remove direct memory access of structures
- - any remaining sparse and checkpatch.pl warnings
-
- - use net_device_ops
- - use dev->stats rather than adapter->stats
- - don't cast netdev_priv it is already void
- - GET RID OF MACROS
- - work on all architectures
- - without CONFIG_X86_64 confusion
- - do 64 bit correctly
- - don't depend on order of union
- - get rid of ASSERT(), use BUG() instead but only where necessary
- looks like most aren't really useful
- - no new SIOCDEVPRIVATE ioctl allowed
- - don't use module_param for configuring interrupt mitigation
- use ethtool instead
- - reorder code to elminate use of forward declarations
- - don't keep private linked list of drivers.
- - use PCI_DEVICE()
- - do ethtool correctly using ethtool_ops
- - NAPI?
- - wasted overhead of extra stats
- - state variables for things that are
- easily available and shouldn't be kept in card structure, cardnum, ...
- slotnumber, events, ...
- - volatile == bad design => bad code
- - locking too fine grained, not designed just throw more locks
- at problem
