      netxen: clean up unnecessary MSI/MSI-X capability find · b83082e9
      由 Yijing Wang 提交于 
      PCI core will initialize device MSI/MSI-X capability in
pci_msi_init_pci_dev(). So device driver should use
pci_dev->msi_cap/msix_cap to determine whether the device
support MSI/MSI-X instead of using
pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX).
Access to PCIe device config space again will consume more time.

      netxen: write IP address to firmware when using bonding · 8a7fbfab
      由 nikolay@redhat.com 提交于 
      This patch allows LRO aggregation on bonded devices that contain an
NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave)
macro which executes for each slave that has bond as master.

V3: After testing and discussing this with Rajesh, I decided to keep the
    vlan ip cache and just rename it to ip_cache since it will store bond
    ip addresses too. A new master flag has been added to the ip cache to
    denote that the address has been added because of a master device.
    I've taken care of the enslave/release cases by checking for various
    combinations of events and flags (e.g. netxen has a master, it's a
    bond master and it's not marked as a slave means it is being enslaved
    and is dev_open()ed in bond_enslave).
    I've changed netxen_free_ip_list() to have a "master" parameter which
    causes all IP addresses marked as master to be deleted (used when a
    netxen is being released). I've made the patch use the new upper
    device API as well. The following cases were tested:
    - bond -> netxen
    - vlan -> netxen
    - vlan -> bond -> netxen

V2: Remove local ip caching, retrieve addresses dynamically and
    restore them if necessary.

Note: Tested with NX3031 adapter.

      netxen: qlogic ethernet : Fix endian bug. · 06d6c108
      由 Santosh Nayak 提交于 
      Change the datatype of "ip_addr" to __be32 as 'ip' should be in
big endian format.

Adapter needs "ip address" in big endian format stored at lower 32bit
of req.word[1]. netxen_config_ipaddr() now receives 'ip' in big endian
format. To satisfy adapter's need, use memcpy() to copy byte by byte
of 'ip' into lower 32bit of req.word[1].

Mac address and serial number of adapter need to be in little endian format.
Change the data type of the related  variables to __le32 / __le64 or cast it
explicitly to __le32 / __le64 depending upon the requirement.

      drivers/net: Remove IRQF_SAMPLE_RANDOM flag from network drivers · ab392d2d
      由 Javier Martinez Canillas 提交于 
      The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed.

Every input point to the kernel's entropy pool have to better document the
type of entropy source it is.

drivers/char/random.c now implements a set of interfaces that can be used for
devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced
with these add_*_randomness exported functions.

Network drivers are not a good source of entropy. They use as a source of
entropy essentially a remote host. Which means that the source of entropy can
be potentially controlled by an attacker. Also, with heavy workloads the
entropy decreases due to less hardware interrupts happening thanks to irq
mitigation and NAPI.

If a system relies in its network interface as a entropy source it has a false
sense of security. Systems that don't have devices whose drivers are good
sources of entropy, should either use a hardware random number generator or
feed the kernel's entropy pool from userspace using other sources of entropy
such as EGD, video_entropyd, timer_entropyd and audio-entropyd.
