2012-01-31net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-05-22Add appropriate <linux/prefetch.h> include for prefetch usersPaul Gortmaker
After discovering that wide use of prefetch on modern CPUs could be a net loss instead of a win, net drivers which were relying on the implicit inclusion of prefetch.h via the list headers showed up in the resulting cleanup fallout.

The driver used to call phy's ethtool configuration routine to start auto-negotiation. This change has it call directly phy's routine to start auto-negotiation.

2011-04-29ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny
This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-04-11stmmac: fix Transmit Underflow errorGiuseppe CAVALLARO
On some old MAC chips without COE sometime the Transmit Underflow error is issued. The driver aborted all the transmission process and initialized it from scratch. This breaks the network activity as raised by Nachiketa on a SPEAr board. The patch is to fix this rare underflow event. The driver will only clear the interrupt and the Tx DMA will go out the Suspend state as soon as the descriptor is fetched again. The driver will continue to bump-up the DMA FIFO threshold that, indeed, helped somebody to prevent this kind of error in the past as well.

2011-04-10net: stmmac: convert to hw_featuresMichał Mirosław
This also removes TSO as it's made fully in software --- better to leave this to networking core. If the MAC features can be detected at probe time and not at open, then stmmac_fix_features could be simplified by limiting hw_features. That's also better for users as they don't see offloads being togglable but never turned on. Redundant fallbacks for TX csum are removed as it's already handled by network core.

2010-09-17stmmac: consolidate and tidy-up the COE supportGiuseppe CAVALLARO
The first version of the driver had hard-coded the logic for handling the checksum offloading. This was designed according to the chips included in the STM platforms where: o MAC10/100 supports no COE at all. o GMAC fully supports RX/TX COE. This is not good for other chip configurations where, for example, the mac10/100 supports the tx csum in HW or when the GMAC has no IPC. Thanks to Johannes Stezenbach; he provided me a first draft of this patch that only reviewed the IPC for the GMAC devices. This patch also helps on SPEAr platforms where the MAC10/100 can perform the TX csum in HW. Thanks to Deepak SIKRI for his support on this. In the end, GMAC devices for STM platforms have a bugged Jumbo frame support that needs to have the Tx COE disabled for oversized frames (due to limited buffer sizes). This information is also passed through the driver's platform structure.

2010-07-27stmmac: fix automatic PAD/FCS strippingGiuseppe CAVALLARO
For Simple Ethernet frames (802.2 and 802.3) the GMAC Core never strips pad and fcs. This means the ACS has no effect on IPv4/6 frames. The FL bits, in the RDES0, include the FCS so the driver has to remove it in SW. For 802.3 frame format with LLC or LLC-SNAP, when set the ACS bit, the HW strips both PAD and FCS. The FL bits, in the RDES0, actually represents the frame length already stripped. This patch fixes this logic within the device driver that erroneously removed 4byte from 802.3 frames already stripped corrupting the payload.
