      Prabhu.

  10) Add stack depth tracking to BPF verifier and use this information
      in the various eBPF JITs. From Alexei Starovoitov.

  14) For loads, allow narrower accesses in bpf verifier checking, from
      Yonghong Song.

  15) Support MIPS in the BPF selftests and samples infrastructure, the
      MIPS eBPF JIT will be merged in via the MIPS GIT tree. From David
      Daney.

  16) Support kernel based TLS, from Dave Watson and others.

  17) Remove completely DST garbage collection, from Wei Wang.

  18) Allow installing TCP MD5 rules using prefixes, from Ivan

  20) Add support for TC flower offload in nfp driver, from Simon
      Horman, Pieter Jansen van Vuuren, Benjamin LaHaise, Jakub
      Kicinski, and Bert van Leeuwen.

  21) IPSEC offloading support in mlx5, from Ilan Tayari.

  22) Add HW PTP support to macb driver, from Rafal Ozieblo.

  23) Networking refcount_t conversions, From Elena Reshetova.

  24) Add sock_ops support to BPF, from Lawrence Brako. This is useful
      for tuning the TCP sockopt settings of a group of applications,
      currently via CGROUPs"

 /**
+ * DOC: WPA/WPA2 EAPOL handshake offload
+ *
+ * By setting @NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag drivers
+ * can indicate they support offloading EAPOL handshakes for WPA/WPA2
+ * preshared key authentication. In %NL80211_CMD_CONNECT the preshared
+ * key should be specified using %NL80211_ATTR_PMK. Drivers supporting
+ * this offload may reject the %NL80211_CMD_CONNECT when no preshared
+ * key material is provided, for example when that driver does not
+ * support setting the temporal keys through %CMD_NEW_KEY.
+ *
+ * Similarly @NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_1X flag can be
+ * set by drivers indicating offload support of the PTK/GTK EAPOL
+ * handshakes during 802.1X authentication. In order to use the offload
+ * the %NL80211_CMD_CONNECT should have %NL80211_ATTR_WANT_1X_4WAY_HS
+ * attribute flag. Drivers supporting this offload may reject the
+ * %NL80211_CMD_CONNECT when the attribute flag is not present.
+ *
+ * For 802.1X the PMK or PMK-R0 are set by providing %NL80211_ATTR_PMK
+ * using %NL80211_CMD_SET_PMK. For offloaded FT support also
+ * %NL80211_ATTR_PMKR0_NAME must be provided.
