[PATCH 0/2] enic fixes for clang compilation

[Bruce Richardson]

Compiling latest DPDK with clang 3.3 on FreeBSD 10 shows up a number of compilation
errors in the enic driver. These two small patches fix those errors.

Bruce Richardson (2):
  enic: fix initialization error with clang
  enic: fix error with uninitialized variable.

[PATCH 1/2] enic: fix initialization error with clang

[Bruce Richardson]

This patch fixes the following compiler error raised by clang 3.3
on FreeBSD 10:

  CC enic_clsf.o
/usr/home/bruce/dpdk.org/lib/librte_pmd_enic/enic_clsf.c:99:25: fatal error: missing field 'u' initializer [-Wmissing-field-initializers]
        struct filter fltr = {0};

It fixes it by changing the initializer to set a named field to zero,
thereby automatically setting the rest of the unnamed fields also to
zero.

[PATCH 2/2] enic: fix error with uninitialized variable.

[Bruce Richardson]

The variable notify_pa is only initialized inside one branch of
an if statement, triggering a compiler error with clang 3.3 on FreeBSD.

  CC vnic/vnic_dev.o
/usr/home/bruce/dpdk.org/lib/librte_pmd_enic/vnic/vnic_dev.c:777:6: fatal error: variable 'notify_pa'
      is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        if (!vnic_dev_in_reset(vdev)) {

Fix this issue by adding "= 0" to the variable definition.

Sorry for the delay.  Was away for a couple of days.
