Subject: [PATCH v4 net-next 0/4] ionic: on-chip descriptors

We start with a couple of house-keeping patches that were originally
presented for 'net', then we add support for on-chip descriptor rings
for tx-push, as well as adding support for rx-push.

I have a patch for the ethtool userland utility that I can send out
once this has been accepted.

v4: added rx-push attributes to ethtool netlink
    converted CMB feature from using a priv-flag to using ethtool tx/rx-push

v3: edited commit message to describe interface-down limitation
    added warn msg if cmb_inuse alloc fails
    removed unnecessary clearing of phy_cmb_pages and cmb_npages
    changed cmb_rings_toggle to use cmb_inuse
    removed unrelated pci_set_drvdata()
    removed unnecessary (u32) cast
    added static inline func for writing CMB descriptors

v2: dropped the rx buffers patch

Shannon Nelson (4):
  ionic: remove unnecessary indirection
  ionic: remove unnecessary void casts
  net: ethtool: extend ringparam set/get APIs for rx_push
  ionic: add tx/rx-push support with device Component Memory Buffers
