Summaries and Symptoms

This patch updates the misc-drivers VIB to resolve the following issues:

PR 747835: FCoE switch can return VLAN ID 4095 in response to the first FIP VLAN discovery request coming from an initiator. However, VLAN ID 4095 is a reserved ID. When ESXi accepts the VLAN ID 4095 from a FCoE switch, ESXi stops FIP VLAN discovery requests and uses this VLAN ID causing FCoE switch to stop functioning.
PR 862366: A race condition in libata driver can cause it to fail in function ata_hsm_move with purple diagnostic screen and with a stack trace similar to following.
BUG: failure at vmkdrivers/src_9/drivers/ata/libata-core.c:5833/ata_hsm_move()!
