2015-02-12drivers/net: Use setup_timer and mod_timerVaishali Thakkar1-5/+2

2014-10-073c59x: fix bad split of cpu_to_le32(pci_map_single())Sylvain "ythier" Hitier1-1/+1
In commit 6f2b6a3005b2c34c39f207a87667564f64f2f91a, # 3c59x: Add dma error checking and recovery the intent is to split out the mapping from the byte-swapping in order to insert a dma_mapping_error() check.

2014-09-203c59x: Fix bad offset spec in skb_frag_dma_mapNeil Horman1-1/+1
Recently aded the use of skb_frag_dma_map to 3c59x, but didn't realize it automatically included the frag_offset internally, as well as provided an option to specify an extra offset in the parameter list. We need to specify an offset of 0 in the parameter list to avoid skb corruption that results in lost connections.

2014-09-203c59x: Add dma error checking and recoveryNeil Horman1-9/+41
Noted that 3c59x has no checks on transmit for failed DMA mappings, and no ability to unmap fragments when a single map fails in the middle of a transmit. This patch provides error checking to ensure that dma mappings work properly, and unrolls an skb mapping if a fragmented skb transmission has a mapping failure to prevent leaks.

It seems on 32 bit kernels page_address() can reutrn a NULL value in some circumstances, and the pci_map_single api isn't prepared to handle that (on this system it results in a bogus pointer deference in nommu_map_page. The fix is pretty easy, if we convert the 3c59x driver to use the more convieient skb_frag_dma_map api we don't need to find the virtual address of the page at all, and page gets mapped to the hardware properly.

2014-04-08Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König1-1/+1
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT.

2013-04-303c509.c: call SET_NETDEV_DEV for all device types (ISA/ISAPnP/EISA)Matthew Whitehead1-0/+2
The venerable 3c509 driver only sets its device parent in one case, the ISAPnP one. It does this with the SET_NETDEV_DEV function. It should register with the device hierarchy in two additional cases: standard (non-PnP) ISA and EISA. - Currently they appear here: /sys/devices/virtual/net/eth0 (standard ISA) /sys/devices/virtual/net/eth1 (EISA) - Rather, they should instead be here: /sys/devices/isa/3c509.0/net/eth0 (standard ISA) /sys/devices/pci0000:00/0000:00:07.0/00:04/net/eth1 (EISA) Tested on ISA and EISA boards.

2013-04-19net: vlan: add protocol argument to packet tagging functionsPatrick McHardy1-1/+1
Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-01-22drivers/net: delete old 8bit ISA 3c501 driver.Paul Gortmaker4-1003/+0
It was amusing that linux was able to make use of this 1980's technology on machines long past its intended lifespan, but it probably should go now. To set some context, the 3c501 was designed in the 1980's to be used on 8088 PC-XT 8bit ISA machines. It was built using a large number of discrete TTL components and truly looks like a relic of the ancient past before large scale integration was common. But from a functional point of view, the real issue, as stated in the (also obsolete) Ethernet-HowTo, is that "...the 3c501 can only do one thing at a time -- while you are removing one packet from the single-packet buffer it cannot receive another packet, nor can it receive a packet while loading a transmit packet." You know things are not good when the Kconfig help text suggests you make a cron job doing a ping every minute. Hardware that old and crippled is simply not going to be used by anyone in a time where 10 year old 100Mbit PCI cards (that are still functional) are largely give-away items.
