Flow control implementation is split to be done in each PHY function. Signed-off-by:

Yaniv Rosner authored
In previous patch, common PHY functions were split in simple way to allow easy diff. This patch comes to align code in the new functions. In addition, the non-production BCM8072 PHY was removed. Signed-off-by:

Yaniv Rosner authored
Move the code into PHY oriented functions, and for that a new structure is defines for each PHY which contain PHY properties and its own functions. This also enables to encapsulate all PHY specific operations into the PHY functions. During initialization, the PHYs will be probed by the "bnx2x_phy_probe" function to detect which PHYs exist on-board, and configure them accordingly. Note that the ext_phy_reset implementation was incorporated in the ext_phy_init since it is actually part of the PHY initialization procedure. Signed-off-by:

This patch standardizes caif message logging prefixes. Add #define pr_fmt(fmt) KBUILD_MODNAME ":%s(): " fmt, __func__ Add missing "\n"s to some logging messages Convert pr_warning to pr_warn This changes the logging message prefix from CAIF: to caif: for all uses but caif_socket.c and chnl_net.c. Those now use their filename without extension. Signed-off-by:

The function has an unsigned return type, but returns a negative constant to indicate an error condition. The result of calling the function is always stored in a variable of type (signed) int, and thus unsigned can be dropped from the return type. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Signed-off-by:

This showed up in my audit because we use strcpy() to copy "ds" into a 32 character buffer inside the isdn_tty_dial() function. But it turns out that we only ever use the first 32 characters so it's OK. I have changed the declaration to make the static checkers happy. Signed-off-by:

cs->ics.parm.setup.phone is a 32 character array. In each of these cases we're copying from a 35 character array into a 32 character array so we should use strlcpy() instead of strcpy(). Signed-off-by:

pskb_expand_head() blindly takes references on fragments before calling skb_release_data(), potentially releasing these references. We can add a fast path, avoiding these atomic operations, if we own the last reference on skb->head. Based on a previous patch from David Signed-off-by:

This patch enables TCP checksum offload support for IPv6 on ibmveth. This completely eliminates the generation and checking of the checksum for IPv6 packets that are completely virtual and never touch a physical network. A basic TCPIPV6_STREAM netperf run showed a ~30% throughput improvement when an MTU of 64000 was used. This featured is enabled by default, as is the case for IPv4 checksum offload. When checksum offload is enabled the driver will negotiate IPv4 and IPv6 offload with the firmware separately and enable what is available. As long as either IPv4 or IPv6 offload is supported and enabled the device will report that checksum offload is enabled. The device stats, available through ethtool, will display which checksum offload features are supported/enabled by firmware. Performance testing against a stock kernel shows no regression for IPv4 or IPv6 in terms of throughput or processor utilization with checksum disabled or enabled. Signed-off-by:

Remove code in the device probe function where we set up the checksum offload feature and replace it with a call to an existing function that is doing the same. This is done to clean up the driver in preparation of adding IPv6 checksum offload support. Signed-off-by:

On some machines we can improve the bandwidth by ensuring rx buffers are not in the cache. Add a module option that is disabled by default that flushes rx buffers on insertion. Signed-off-by:

ibmveth can scatter gather up to 6 segments. If we go over this then we have no option but to call skb_linearize, like other drivers with similar limitations do. Signed-off-by:

Use the existing bounce buffer if we send a buffer under a certain size. This saves the overhead of a TCE map/unmap. I can't see any reason for the wmb() in the bounce buffer case, if we need a barrier it will be before we call h_send_logical_lan but we have nothing in the common case. Remove it. Signed-off-by:

The ibmveth adapter needs locking in the transmit routine to protect the bounce_buffer but it sets LLTX and forgets to add any of its own locking. Just remove the deprecated LLTX option. Remove the stats lock in the process. Signed-off-by:

At the moment we try and replenish the receive ring on every rx interrupt. We even have a pool->threshold but aren't using it. To limit the maximum latency incurred when refilling, change the threshold from 1/2 to 7/8 and reduce the largest rx pool from 768 buffers to 512 which should be more than enough. Signed-off-by:
