2012-02-13sfc: Warn if unable to create MTDsBen Hutchings
Log an explicit warning if we are unable to create MTDs for a net device. Also correct the comment about why mtd_device_register() may fail; there is no longer an MTD table to fill up. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-13sfc: Replace some literal constants with EFX_PAGE_SIZE/EFX_BUF_SIZEBen Hutchings
The 'page size' for PCIe DMA, i.e. the alignment of boundaries at which DMA must be broken, is 4KB. Name this value as EFX_PAGE_SIZE and use it in efx_max_tx_len(). Redefine EFX_BUF_SIZE as EFX_PAGE_SIZE since its value is also a result of that requirement, and use it in efx_init_special_buffer(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-13sfc: Do not retry hardware probe if it schedules a resetBen Hutchings
If efx_pci_probe_main() schedules an INVISIBLE or ALL reset (but nothing more drastic), we retry it up to 5 times. So far as I'm aware, this was a workaround for bugs in Falcon A0 which were fixed in production silicon. Remove the retry. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-13sfc: Skip RX end-of-batch work on channels without an RX queueBen Hutchings
The code in efx_process_channel() to update the RX queue after each batch of RX completions works out as a no-op on a TX-only channel where the RX queue structure is set to all-zeroes, but (1) efx_channel_get_rx_queue() will BUG() if DEBUG is defined, and (2) it's a waste of time.

2012-02-13e1000e: cleanup goto statements to exit points without common workBruce Allan
Per ./Documentation/CodingStyle, goto statements are acceptable for the centralized exiting of functions when there are multiple exit points which share common work such as cleanup. When no common work is required for multiple exit points, the function should just return at these exit points instead of doing an unnecessary jump to a centralized return. This patch cleans up the inappropriate use of goto statements, and removes unnecessary variables (or move to a smaller scope) where possible as a result of the cleanups.

2012-02-13fec: fix PHY name to match fixed MDIO bus nameFlorian Fainelli
Commit "391420f7: fec: use an unique MDIO bus name" first modified the MDIO bus name to include the platform name, then in commit "a7ed07d5: net: fec: correct phy_name buffer length when init phy_name" the PHY name formatting was fixed in the case the PHY matches a PHY driver. The FEC driver however, also handles the case where we want to attach to the fixed MDIO bus name, which was previously named "0", and now "fixed-0".

2012-02-13enic: remove assignment of random mac on enic vfRoopa Prabhu
This patch removes random mac assignment on vf's. The vf's will start with a zero mac and with upcoming support in fw/driver, a vf mac can be set via the pf. vf's also support ndo_set_mac_address. This decision was made based on the fact that a random mac on a vf is not really needed. And this will reduce some of the problems with the vf's getting a new mac on every driver load/unload (one of them being udev renaming the device on ever load/unload and reboot).

2012-02-13be2net: event queue re-designSathya Perla
v2: Fixed up the bad typecasting pointed out by David... In the current design 8 TXQs are serviced by 1 EQ, while each RSS queue is serviced by a separate EQ. This is being changed as follows: - Upto 8 EQs will be used (based on the availabilty of msix vectors). Each EQ will handle 1 RSS and 1 TX ring. The default non-RSS RX queue and MCC queue are handled by the last EQ. - On cards which provide support, upto 8 RSS rings will be used, instead of the current limit of 4. The new design allows spreading the TX multi-queue completion processing across multiple CPUs unlike the previous design. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2012-02-13rename dev_hw_addr_random and remove redundant secondDanny Kukawka
Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that this function only assign a random ethernet address (MAC). Removed the second parameter (u8 *hwaddr), it's redundant since the also given net_device already contains net_device->dev_addr. Set it directly. Adapt igbvf and ixgbevf to the changed function. Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails (which means the device got no dev_addr) handle the error and jump to err_sw_init as already done by igbvf in similar case.
