2018-07-27net: amd: pcnet32: Replace GFP_ATOMIC with GFP_KERNEL in pcnet32_alloc_ring()Jia-Ju Bai1-4/+4
pcnet32_alloc_ring() is never called in atomic context. It calls kcalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-02-14pcnet32: fix BNC/AUI port on AM79C970AOndrej Zary1-52/+125
Even though the port autoselection is enabled by default on AM79C970A, BNC/AUI port does not work because the link is always reported to be down. The link state reported by the chip belongs only to the TP port but the driver uses it regardless of the port used. The chip can't detect BNC/AUI link state. Disable port autoselection and use TP port by default to keep current behavior (link detection works on TP port, BNC/AUI port does not work). Implement ethtool autoneg, port and duplex configuration to allow using the BNC/AUI port. Report the TP link state only if the TP port is selected. When the port autoselection is enabled or AUI port is selected, report the link as always up. Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid forward declarations.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson1-1/+0
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

2015-11-10pcnet32: use pci_set_dma_mask insted of pci_dma_supportedChristoph Hellwig1-1/+1
All drivers should be using dma_set_mask / pci_set_dma_mask to try to set the dma mask instead of just querying it. Without that some iommu implementations may not work. pci_dma_supported is removed entirely, but dma_supported stays for dma_ops implementations for now. This patch (of 15): This ensures the dma mask that is supported by the driver is recorded in the device structure.

2015-03-20Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller1-2/+29
Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-20net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5}Markos Chandras1-2/+29
On a MIPS Malta board, tons of fifo underflow errors have been observed when using u-boot as bootloader instead of YAMON. The reason for that is that YAMON used to set the pcnet device to SRAM mode but u-boot does not. As a result, the default Tx threshold (64 bytes) is now too small to keep the fifo relatively used and it can result to Tx fifo underflow errors. As a result of which, it's best to setup the SRAM on supported controllers so we can always use the NOUFLO bit.

2015-01-19mii: Handle link state changes for forced modes in mii_check_media()Ben Hutchings1-1/+1
mii_check_media() does not update the link (carrier) state or log link changes when the link mode is forced. Drivers using the mii library must do this themselves, but most of them do not. Instead of changing them all, provide a sensible default behaviour similar to mii_check_link() when the mode is forced. via-rhine depends on it being a no-op in this case, so make its call to mii_check_media() conditional.
