[V2,6/9] qtnfmac: convert "Append IEs" command to QTN_TLV_ID_IE_SET usage

Commit Message

Igor Mitsyanko Oct. 31, 2017, 1:04 a.m. UTC

From: Igor Mitsyanko <[e-mail]>

Data contained within "Append IEs" command (QLINK_CMD_MGMT_SET_APPIE)
duplicates QTN_TLV_ID_IE_SET TLV. Convert the command to use that TLV
instead.
